Abstract :
A simple but very useful approach based on network transposition principle is presented to derive new CMOS sinusoidal oscillators using operational transconductance amplifiers and capacitors (OTA-C). The principle of mirroring to convert a three-terminal two-port network to a four-terminal fully differential network is utilized to generate fully differential OTA-C oscillator structures. The theoretical work is verified by using discrete resistors, capacitors and OTA devices.
