摘要： A switched capacitor is provided. The switched capacitor includes a pair of parallel component stacks. Each stack is connected to a common top node and a common bottom node. Each stack includes a BJT. Each stack further includes a first resistor in series with the BJT and having a first side connected to a collector of the BJT at an intermediate node in a same one of the stacks and a second side connected to the common top node. Each stack also includes a capacitor having a first side connected to the intermediate node and a second side for providing an impedance. Each stack additionally includes a second resistor having a first side connected to a base of the BJT to prevent base-current surge in the BJT and a second side connected to a switch base control signal that selectively turns the BJT on or off.

摘要： An isolated power transfer device includes a transformer formed in a multi-layer substrate of an integrated circuit package. A primary winding of the transformer is coupled to a first integrated circuit to form a DC/AC power converter and a secondary winding of the transformer is coupled to a second integrated circuit to form an AC/DC power converter. The first and second integrated circuits are electrically isolated from each other. The first integrated circuit includes a lightly doped drain MOSFET integrated with conventional CMOS devices and the second integrated circuit includes a Schottky diode integrated with conventional CMOS devices. The isolated power transfer device includes a capacitive channel for communication of information across an isolation barrier from the second integrated circuit to the first integrated circuit. Capacitors of the capacitive channel may be formed in the multi-layer substrate of the integrated circuit package.

摘要： A transceiver may include a reception (Rx) radio frequency (RF) part configured to process a received signal, a transmission (Tx) RF part configured to process a transmitted signal, and a phase lock loop (PLL) configured to provide a reception frequency to the reception RF part and provide a transmission frequency to the transmission RF part.

In addition, a transceiver may include quenching waveform generator (QWGs) to control quenching waveforms of the RF parts corresponding to a plurality of antennas. The quenching waveforms may be generated respectively by VCOs operating at a same frequency. The QWGs may control the VCOs such that the quenching waveforms do not overlap.

摘要： A crystal oscillator circuit is configured to output an oscillation signal. A bias circuit responds to control signal to generate a bias current for application to the crystal oscillator circuit. A current generator generates a sense current from the control signal. The sense current is compared to a reference current by a comparator circuit. The comparator circuit generates a ready signal in response to the comparison. The ready signal is indicative of whether the oscillation signal output from the crystal oscillator circuit is ready for use by other circuitry. The reference current may be generated by a circuit which replicates the bias circuit.

摘要： Multi-mode oscillators supporting multiple modes and having different desirable characteristics (e.g., good phase noise or low power consumption) in different modes are disclosed. In an exemplary design, an apparatus includes first and second transistors of a first transistor type (e.g., NMOS transistors) and third and fourth transistors of a second transistor type (e.g., PMOS transistors) for a multi-mode oscillator. The third and fourth transistors are coupled (e.g., directly) to the first and second transistors. The first and second transistors are enabled in a first mode to provide signal gain for the oscillator and generate an oscillator signal in the first mode. The first to fourth transistors are enabled in a second mode to provide signal gain for the oscillator and generate the oscillator signal in the second mode. Different supply voltages may be provided at different supply nodes of the oscillator in the first and second modes.

摘要： Apparatus and methods are also disclosed related to an oscillator that includes a switching network configured to tune a resonant frequency of a resonant circuit. One such apparatus includes a switching network having a circuit element, such as a capacitor, that can be selectively coupled to the resonant circuit by a switch, such as a field effect transistor. For instance, the switch can electrically couple to circuit element to the resonant circuit when on and not electrically couple the circuit element to the resonant circuit when off. An active circuit can assert a high impedance on an intermediate node between the switch and the circuit element when the switch is off.
