A PVT-compensated sinusoidal wave generator with phase modulation for multi-channel sensor applications

Abstract

This paper presents a PVT-compensated sinusoidal wave generator exploiting phase modulation for multi-channel sensor applications. The sinusoidal wave is generated by a DDFS with a PVT-compensated relaxation oscillator. The sinusoidal wave generator is fabricated in 0.18 μm CMOS technology, occupying an active area of 1.099 mm2 with a power consumption of1.55 mW.
