Abstract
Energy-efficient timing circuits are described. Such circuits may include a biasing circuit configured to provide a control bias current to a voltage-controlled oscillator (VCO). The biasing circuit may repetitively switch between a normal-power operating mode and a reduced-power operating mode. During the normal-power operating mode, the biasing circuit may generate a control voltage representative of a desired control bias current for the VCO. By then storing the control voltage using a device, such as a capacitor, much of the biasing circuit may be turned off during the reduced-power operating mode.
