    摘要： A common dual-mode physical layer architecture for a communications receiver is capable of receiving either frequency hopping spread spectrum signals or direct sequence spread spectrum signals. A delta-sigma modulator is configured as an oversampling A/D converter with predetermined quantization noise shaping characteristics. The respective spread spectrum signal is processed by the delta-sigma modulator and then filtered via a decimation filter such as a (sin(x))/x filter to generate a quadrature signal having sufficient resolution to meet industry standards.

    摘要： A current source (10) for use on an integrated circuit chip (14), particularly in conjunction with CMOS circuits or the like, includes a first MOS transistor (12), having a gate to control a current in a current flow path therethrough. A second MOS transistor (13) having a gate to control a current in a current flow path therethrough between a supply voltage and a reference potential is connected to the gate of the first MOS transistor (12). A current source (16) is connected at a connection node to the first MOS transistor (12) to supply a current in the current flow path of the first MOS transistor (12) to hold the first MOS transistor (12) on. The gate of the first MOS transistor (12) is connected to the connection node. A bias voltage source (V.sub.B) is provided in the current flow path of the first MOS transistor (12) with respect to the reference potential. With the circuit thus configured, the current flowing through the second MOS transistor (13) is essentially independent of the threshold voltage of the second MOS transistor (13). The MOS transistors can be either NMOS or PMOS transistors.

    摘要： An input protection circuit for a MOS device uses back-to-back zener diodes 30 and 40 with the anodes 130 and 150 connected and floating. This circuitry protects against positive and negative ESD events and does not interfere with the normal operation of the MOS device. The inventive circuit allows an improved gate operating range of the forward bias voltage of a first diode 30 plus the breakdown voltage of a second diode 40 below the supply voltage to the breakdown voltage of the first diode 30 plus the forward bias voltage of the second diode 40 above the supply voltage.

    摘要： The described devices, systems and methods include an integrator circuit having two separate operational modes to control a power output level delivered by the power amplifier to an antenna during start of a transmission burst. The first operational mode utilizes a wide bandwidth control loop to pre-charge a capacitor of the integrator circuit, which generates a pedestal voltage delivered to the power amplifier control input. The second operational mode utilizes a lower bandwidth control loop to ensure stable operation of the control loop during normal operation of the power amplifier.

    摘要： A system is provided for adjusting an output power of a multi-stage power amplifier by controlling a supply voltage provided to one or more output amplifier stages of the power amplifier using a switching DC—DC converter. In general, the system includes a power amplifier including an input amplifier stage and one or more output amplifier stages coupled in series with the input amplifier stage. The one or more output amplifier stages receive a variable supply voltage from switching DC—DC conversion circuitry. The switching DC—DC conversion circuitry provides the variable supply voltage based on an adjustable power control signal. By controlling the variable supply voltage provided to the one or more output stages, the switching DC—DC conversion circuitry controls an output power of the power amplifier based on the adjustable power control signal.

    摘要： The multiplication circuitry of the present invention operates to generate multiple monolithic electrical currents, all referenced to a single external resistor. A first current referenced to a first monolithic resistor, a second current referenced to a second monolithic resistor, and a third current referenced to an external resistor are used to generate an output current, which is also referenced to the external resistor. The present invention accurately generates two currents each being referenced to the single external resistor, while simultaneously minimizing the number of external connections and overall cost of producing the circuitry.

    摘要： The present invention is a high efficiency AM switching voltage regulator used to provide an AM output signal to an AM RF power amplifier, wherein the AM output signal is proportional to an AM input signal. The AM output signal includes an AM output voltage and an AM supply current, which represents a sum of an AM output current and a shunt current The AM output voltage provides an envelope supply voltage to the AM RF power amplifier. The switching voltage regulator includes a switching current regulator coupled to a linear shunt voltage regulator. The switching current regulator provides AM output current for the AM RF power amplifier and a small amount of shunt current for the linear shunt voltage regulator, which regulates the AM output voltage by controlling the shunt current. The switching current regulator regulates the AM supply current in proportion to a time-averaged value of shunt current.
