Conventional wireless receivers employing a heterodyne/homodyne architecture or N-path filter often result in significantly higher area and power overhead owing to the requirement of LO generation distribution at high frequencies [1]. Those overheads can be alleviated by uniform sub-sampling (USS) architectures that directly sample RX input signal much lower clock frequency rely on particular harmonic aliasing for downconversion reconstruction [2]. Such require desired strictly bandpass...
This paper presents an analog Kalman filter employing a shared VCO scheme that takes sensor data from gyroscope and accelerometer as input generates digitized estimate of the attitude via fusion. The VCO-based integrator ADC are designed to consume minimal power implementation overhead by sharing CMOS thyristor-based operating in subthreshold region. silicon prototype is fabricated 65 nm technology achieves 0.8° RMSE using real data, embedded measures 51.58 dB SNDR 57.28 SFDR under single-tone test.
Sensing or communication using the millimeter (mm)-wave band, such as mm-wave 5G systems and radar applications, is drawing increasing research interest. These typically employ an array of power amplifiers (PAs), with each PA operating at moderate output power. In this case, efficiency crucial for better thermal management. Due to high peak-to- average ratios spectrum-efficient modulations, back-off (PBO) becoming increasingly important. The Class E/F switching a favorable candidate...
