ABSTRACT:
An oscillator is provided the frequency of operation of which is controlled by an RC circuit the resistive element of which is an MOS load device and the capacitive element of which is an MOS enhanced capacitor. An important characteristic of this ring oscillator is that its time constant determining elements mutually compensate one another for changes in temperature. A digital enhanced capacitor can be used in this temperature compensated ring oscillator to provide greater flexibility in controlling both the frequency of operation of the oscillator and the wave shape of the output signal.
