Market Opportunity
Modern radiofrequency (RF) communication systems have high spectral efficiency modulations, which lead to large peak to average power ratios (PAPRs). To prevent excessive amplification of these peaks and other nonlinearities, power amplifiers (PAs) need to “back off” from operating at maximum linear power, and instead...

Market Opportunity
Sensing and communication using the millimeter wave band is a promising new approach for applications like mm-wave 5G systems and radar. These systems generally utilize power amplifiers (PAs), the peak and power back-off efficiency of which is crucial for power and thermal management. While class E/F switching PA has emerged as a...

Market Opportunity
In-memory computing (IMC) is a promising alternative to traditional digital machine learning algorithms due to its energy efficiency. Past IMC research used a digital-to-analog converter (DAC) to encode multi-bit input into pulse count, pulse width, or an analog voltage, which has limitations such as static power consumption and...

Market Opportunity
The need for high-speed, medium-resolution analog-to-digital converters (ADCs) is rapidly growing due to the increasing demand for wideband communication integrated circuits. The traditional voltage-domain time- interleaved SAR time-to-digital converter (TDC) is an efficient option, but its single-channel sample rate is limited,...

Abstract
USC researchers have designed a circuit arrangement to accelerate solving of the SAT algorithm. This two-part circuit uses a memory cell to represent values of a Boolean satisfiability expression and a constraints network that modifies the memory cell. The design builds...
