    Abstract: A power amplifier configuration including power amplifier circuitry and power control circuitry and having improved Power Added Efficiency (PAE) is provided. The power amplifier circuitry includes one or more input amplifier stages in series with a final amplifier stage. The power control circuitry provides a variable supply voltage to the input amplifier stages based on an adjustable power control signal. The final amplifier stage is powered by a fixed supply voltage. In operation, as output power of the power amplifier is reduced from its highest power level, the variable supply voltage is reduced. Accordingly, RF power of an amplified signal provided to the final amplifier stage from the input amplifier stages decreases, and the final amplifier stage transitions from saturation to linear operation, thereby increasing the gain of the final amplifier stage. Thus, a desired output level can be maintained while operating at lower current levels.

    Abstract: A battery powered radio device includes a transmitter, a control circuit, and a lockout circuit. The transmitter transmits radio communications and the transmitter includes a power amplifier which generates an amplified radiofrequency output signal. More particularly, the power amplifier uses both a positive supply voltage and a negative bias voltage for operation wherein the negative bias voltage is less than a supply ground voltage. The control circuit enables the power amplifier during transmission, and the control circuit includes a switch coupled in series between a positive supply voltage and the power amplifier. The switch is activated in response to a transmit activation signal when the negative bias voltage is coupled to the power amplifier. The lockout circuit prevents activation of the switch in response to the transmit activation signal when the negative bias voltage is not coupled to the power amplifier. In addition, the switch can be activated in response to a transmit activation signal by applying the negative bias voltage to the switch control gate and deactivated in the absence of the transmit activation signal by applying the positive supply voltage to the switch control gate.

    Abstract: A configurable 2-wire/3-wire serial communications interface (C23SCI), which includes start-of-sequence (SOS) detection circuitry and sequence processing circuitry, is disclosed. When the SOS detection circuitry is coupled to a 2-wire serial communications bus, the SOS detection circuitry detects an SOS of a received sequence based on a serial data signal and a serial clock signal. When the SOS detection circuitry is coupled to a 3-wire serial communications bus, the SOS detection circuitry detects the SOS of the received sequence based on a chip select (CS) signal. In response to detecting the SOS, the SOS detection circuitry provides an SOS detection signal to the sequence processing circuitry, which initiates processing of the received sequence using the serial data signal and the serial clock signal. The received sequence is associated with one of multiple serial communications protocols.
