RF Circuits and System Design from the Perspective of Waveform Level Signal Processing

Abstract:

The demand for high speed, reliable, and high data rate transmission in communication, sensing, artificial intelligence (AI) computing, quantum processing, health, and internet of thing (IoT) are continuously increasing, and upscaling frequency spectrum and improving utilization of spectrum are emerging methodologies to support the urgent needs of data transmission in different applications. These new spectrum and high speed with wide instantaneous bands bring unprecedented challenges for conventional electronic hardware systems. For example, high end multiple analog or digital filters are required in spectrum sensing hardware block, spurious frequency cancellation and low local oscillator frequency feedthrough are designed for frequency conversion block, high sampling rate, wideband, high-resolution analog to digital converters (ADC) are desired for signal conversion, and high-speed baseband processor are applied to execute complex signal processing, which fundamentally limits the operating speed and consume high energy and power. In this talk, a new design approach for RF circuits and system from point of signal processing view will be discussed, and several reconfigurable real time RF signal processing circuits performing mathematical operation directly at analog waveform domain will be discussed to mitigate the computation load in digital domain and signal processing and relax system stringent constraints.
