Title: Nitesh Singhal: Innovator in Power Amplifier Technology
Introduction
Nitesh Singhal is a prominent inventor based in Los Angeles, CA. He has made significant contributions to the field of power amplifier technology, holding 2 patents that showcase his innovative approach to enhancing efficiency in communication systems.
Latest Patents
His latest patents include the "Digital Polar" and "ZVS Contour Based Hybrid Power Amplifier." The Digital Polar patent presents a power amplifier that improves the dynamic range of previous ZVS contour-based power amplifier architectures. This inventive circuit combines ZVS contour-based power amplification with a current mode digital-to-analog converter (DAC) based digital polar power amplifier. The elements interoperate to provide high efficiency even at large peak power back-off levels and increased dynamic range. This invention is particularly well-suited for modulation schemes such as WLAN, LTE, and WIMAX, which have large peak-to-average output power ratios. Utilizing this power amplifier can increase RF transmitter efficiency by approximately two-fold.
The second patent, "Zero-Voltage-Switching Contour Based Outphasing Power Amplifier," describes a zero-voltage-switching contour based outphasing power amplifier. This amplifier consists of two class-E power amplifiers connected in an out-phasing architecture, coupled on opposite sides of a load being driven. The class-E power amplifiers receive separate digital drive signals with a phase difference adjusted based on the load. Variable capacitor arrays are coupled in parallel on the class-E power amplifiers and controlled in response to system parameters, including the duty cycle of the input signal. This design maintains the efficiency of the power amplifier despite variations in output loading.
