Abstract: The present disclosure provides a power amplifier controller for starting up, operating, and shutting down a power amplifier. The power amplifier controller includes current sense amplifier circuitry adapted to monitor a main current of the power amplifier. A bias generator is also included and adapted to provide a predetermined standby bias voltage and an operational bias voltage based upon a main current level sensed by the current sense amplifier circuitry. The power amplifier controller further includes a sequencer adapted to control startup and shutdown sequences of the power amplifier. In at least one embodiment, the power amplifier is a gallium nitride (GaN) device, and the main current level sensed is a drain current of the GaN device. Moreover, the bias generator is a gate bias generator provided that the power amplifier is a field effect transistor (FET) device.

Abstract: Analog-to-digital pulse width modulation circuitry includes thermometer code generator circuitry, clock generator circuitry, delay selection circuitry, and an output stage. The thermometer code generator circuitry is adapted to generate a digital thermometer code based upon a received analog input voltage. The clock generator circuitry is adapted to generate a reference clock and a plurality of delayed clock signals. The delay selection circuitry is connected between the thermometer code generator circuitry and the clock generator circuitry, and is adapted to select one of the delayed clock signals to present to the output stage based upon the generated thermometer code. The selected delayed clock signal is delayed by an amount of time that is proportional to the generated thermometer code. The reference clock signal and the selected delayed clock signal are delivered to the output stage where they are used to generate a pulse width modulated output signal.

The multi-stage filter includes at least a first inductance (L) capacitance (C) filter and a second LC filter coupled in series between the first switching converter and a DC-DC converter output. The first LC filter has a first LC time constant and the second LC filter has a second LC time constant, which is less than the first LC time constant. The first switching converter and the multi-stage filter form a feedback loop, which is used to regulate the first switching power supply output signal based on the setpoint. The first LC filter includes a first capacitive element having a first self-resonant frequency, which is about equal to a first notch frequency of the multi-stage filter.
