Abstract
Apparatus and methods are provided for a temperature-compensated oscillator adapted to receive an input reference current. The apparatus and methods include or provide a temperature coefficient control circuit adapted to adjust the input reference current based on temperature information, wherein the temperature coefficient control circuit receives a first signal corresponding to the temperature information at a first signal node, and a second signal corresponding to a trimmed bias signal at a second signal node.
