摘要： An apparatus, system, and method for voltage regulator (VR) control are provided. An apparatus can include first, second, and third comparators configured to determine whether a load voltage (VLOAD) drops below a lower non-linear control (NLC) threshold, drops below a lower linear control (LC) threshold, and exceeds an upper LC threshold, respectively. The apparatus can include power gates (PGs) configured to adjust an output voltage (VOUT) based on a provided power gate (PG) code. The apparatus can include voltage regulator (VR) controller circuitry comprising synchronous LC circuitry and asynchronous NLC circuitry, the LC circuitry configured to increment or decrement the PG code responsive to the VLOAD dropping below the LC threshold and exceeding the upper LC threshold, respectively, and the NLC circuitry configured to increase the PG code based on a number of consecutive NLC droop events and responsive to the VLOAD dropping below the lower NLC threshold.

摘要： A reduced-size replica of power gate transistors may be used within a closed-loop voltage regulator to measure the average current delivered by the transistors in the non-replica power gate. The measured current is compared against a known reference current, and a feedback loop is used to modify the gate bias of the power gate and replica power gate transistors. An improved current sensing power gate replica solution may include measuring current from a small replica of the power gate and extrapolating the total current by digitally multiplying the replica current by the ratio of the size of the enabled power gates to the size of the replicas. The current through the replicas, which substantially matches the current in equivalent power gate devices, may be collected on an analog bus and conducted across a known resistor to generate a voltage that determines an estimated current of the power gate devices.

摘要： An RF power amplifier system comprises an amplitude control loop and a phase control loop. The amplitude control loop adjusts the supply voltage to the power amplifier based upon the amplitude correction signal indicating the amplitude difference between the amplitude of the input signal and an attenuated amplitude of the output signal. The phase control loop adjusts the phase of the input signal based upon a phase error signal indicating a phase difference between phases of the input signal and the output signal. The phase control loop may comprise one or more variable phase delays introducing a relative phase delay to allow the phase differences between the input and output signals of the PA circuit to be within a range compatible with a phase comparator generating the phase error signal, and a low frequency blocking module that removes the larger extent, lower frequency components of the phase error signal.
