Most oscillator circuits include a nonlinear amplitude control that sustains oscillations at a desired amplitude with minimum output distortion. One approach uses the output sinusoid's amplitude to ...

Milpitas, Calif. – Two 2.7- to 5.5-volt single-supply, 20-bit differential delta-sigma analog-to-digital converters from Linear Technology Corp. include an oscillator that needs no external ...

To validate this technique, a differential amplifier with noise cancellation was implemented as a ring oscillator in a CMOS test chip together with a second ring oscillator built using ...
