摘要：
A semiconductor device or a circuit includes a controllable oscillator and circuitry that senses a voltage which may control the controllable oscillator and digitally controls a gain compensation, adaptively compensating for a drop in a gain against overall loop gain within a closed loop. In one embodiment, a single supply source may be used to power the closed loop while a variable gain stage that is digitally controllable may adjust the gain in a feed-forward manner based on the drop.
