A low power CMOS current steering multivibrator VFC with full scale input

This paper presents a low power CMOS current steering multivibrator based VFC, which can be used for analog front end interfacing of sensors in telemetry applications. The proposed circuit is designed in 180 nm CMOS technology with 1.8V power supply. It operates at full scale input voltage range and the output frequency ranges from 0.38MHz to 4.69MHz. The peak total power consumption observed is 182.5 μW.
