Abstract: A method and apparatus for reducing parasitic capacitance. A P-well blocked layer is formed directly beneath a parasitic device. The P-well blocked layer significantly increases the resistance underneath the parasitic device. The resistance of the P-well blocked layer, in effect, partially disconnects the parasitic device from the ground terminal to minimize the effective capacitive impedance that is added to the total termination impedance.

Abstract: The multi-mode phase and data detector includes a phase detector and a charge pump. A plurality of latching blocks clocked on complimentary phases of a feedback signal produces a plurality of phase and transition signals. Based on a selectable bias level, latched comparators in the latching blocks operate to detect the multi-level input data signal as it crosses a plurality of threshold levels. Logic within the multi-mode phase and data detector selects subsets of exclusive OR gates from sets of exclusive OR gates and subsets of the latching comparators to place the multi-mode phase and data detector in one of a PAM-4, NRZ, or PRML mode of operation. The logic further selects subsets of latched comparators from the plurality of parallel coupled latches to further define the mode of operation of the multi-mode phase and data detector.

Abstract: Integrated circuits, key components in thousands of products, frequently include thousands and even millions of microscopic transistors and other electrical components. Because of difficulties and costs of fabricating these circuits, circuit designers sometimes ask fabricators to produce skew lots for testing and predicting manufacturing yield. However, conventional skew lots for CMOS circuits, which are based on increasing or decreasing transistor transconductance, are not very useful in testing certain types of analog circuits, such as oscillators. Accordingly, the present inventors developed a new type of skew lot, based on increasing or decreasing gate-to-source capacitance of transistors, or more generally a transistor characteristic other than transconductance. This new type of skew lot is particularly suitable for simulating, testing, and/or making yield predictions for oscillators and other CMOS analog circuits.

Abstract: A high-speed, wide bandwidth data detection circuit includes a phase detection module, a data detection module, a loop filter, and a voltage controlled oscillator. The phase detection module is operably coupled to produce a controlled current based on a current mode mathematical manipulation of differences between an incoming data stream and a recovered clock. The phase detection module performs the current mode mathematical manipulations and produces the controlled current in the current domain. The data detection module is operably coupled to produce the detected data based on the incoming data stream and the recovered clock. The loop filter is operably coupled to convert the controlled current into a controlled voltage. The voltage controlled oscillator is operably coupled to convert the control voltage into the recovered clock.

Abstract: A data conveyance integrated system that can be utilized in a base station and/or end user devices in a wireless communication system. The integrated system includes first and second integrated circuits (ICs). The first IC includes a first serial-deserial (SERDES) module, a transmit radio frequency module, and a receive radio frequency module. The transmit and receive radio frequency modules provide the wireless communication between the base stations and end user devices. The second IC includes a second SERDES module and a programmable logic fabric programmed to implement one or more wireless communication functions. Accordingly, the programmable logic fabric generates outbound digital signals from data (e.g., video, audio, control, or text data) provided to the device, and/or processes inbound digital signals to recapture the originally transmitted data. Thus, base stations and/or end user devices within a wireless communication system can be readily reconfigured.

Abstract: Adjustment circuitry in a phase-locked loop (PLL) adjusts a sampling point to any desired location within a bit period of each bit of received high-speed serial data. The adjustment circuitry, responsive to program control, selectively adds current portions to a charge pump error current output thereby adjusting a feedback signal frequency to shift the serial data sampling point. A plurality of current mirror devices is scaled, with respect to a reference current device, to provide ΔI current portions. A current control module controls the current portions magnitude and a sign of the current portions. The adjustment circuitry further controls charge pump programmable current sources in order to set a desired operating point of the PLL. The programmable current sources are controlled by a bias voltage and a plurality of selectable serial and parallel coupled resistors.

Abstract: A clock recovery circuit that operates at a clock speed equal to one-half the input data rate is presented. The clock recovery circuit uses dual input latches to sample the incoming serial data on both the rising edge and falling edge of a half-rate clock signal to provide equivalent full data rate clock recovery. The clock recovery circuit functions to maintain the half-rate clock transitions in the center of the incoming serial data bits. The clock recovery circuit includes a phase detector, charge pump, controlled oscillation module and a feedback module. The phase detector produces information on the phase and data transitions in the incoming data signal to the charge pump. Generally, the circuit is delay insensitive and receives phase and transition information staggered relative to each other.

Abstract: The present invention presents a closed loop system that utilizes a non-linear reference to control a power amplifier's output power in order to obtain a linear transfer function of dB per adjustment step of a reference input. The closed loop system demonstrates that each non-linear stage/step in an automatic gain control system can create a linear closed loop system when using a non-linear reference. The closed loop system of the present invention eliminates the need for a linearization circuit for the system's power detector. The closed loop system may be used with most power amplifiers when linear control in terms of dB vs. adjustment setting of the input reference signal is desired. Output power in terms of dBms can be accurately set in linear steps where power control over a wide dynamic range is desired.
