Latest Patents
One of his latest patents focuses on the linearization and calibration predistortion of a digitally controlled power amplifier. This invention provides an apparatus and method for linearizing a digitally-controlled pre-power amplifier (DPA) and RF power amplifier (PA). It performs predistortion calibration to compensate for nonlinearities in the DPA and PA circuits. The invention utilizes a predistortion look-up table (LUT) that stores measured distortion compensation data, which is applied to the TX data before being input to the digital-to-frequency converter (DFC), DPA, and PA. Additionally, the on-chip receiver demodulates the RF PA output and uses the digital I/Q RX outputs to perform calibration of the TX pre-distortion tables. This innovative approach allows for real-time updates to the predistortion tables based on the instantaneous values of the AM/AM and AM/PM pre-distortion.
Another notable patent involves digital amplitude modulation. This invention features a transmitter using quadrature modulation, which includes a rectangular to polar converter for converting data symbols into polar form. The digital phase modulation circuitry employs an all-digital PLL circuit to generate a phase-modulated RF carrier signal. A digitally controlled amplifier amplifies the phase-modulated signal, with gain controlled by digital amplitude control circuitry.
