Abstract
A new fully integrated two-stage operational transconductance amplifier-capacitor (OTA-C) sine oscillator circuit configuration using a 0.5 μm CMOS digital process is described. A simple linear impedance analysis is presented to predict the amplitude and distortion of oscillation. The accuracy of this approach is examined by comparing calculated, simulated and measured results. Transconductance tuning keeps the startup condition satisfied within the frequency range from 2 to 11 MHz
