Abstract:
An apparatus is disclosed for providing frequency stabilization. The apparatus includes a first supply voltage node, a second supply voltage node, an oscillator circuit coupled to the first supply voltage node, at least one clock buffer coupled to the second supply voltage node and an output of the oscillator circuit, and at least one load circuit. The at least one clock buffer is configured to selectively be in a disabled state or an enabled state to pass the clock signal to at least one client of multiple clients. The at least one load circuit includes an input coupled to the output of the oscillator circuit. The at least one load circuit also includes an output configured to be coupled to a ground. The at least one load circuit is configured to be connected to the first supply voltage node for at least a portion of time.
