Abstract
An oscillator circuit may selectively switch between a normal mode and a low-power mode in response to a mode signal. During the normal mode, the oscillator circuit may employ a first amplifier configuration and a first capacitive loading to generate a high-accuracy clock signal having a relatively low frequency error. During the low power mode, the oscillator circuit may employ a second amplifier configuration and a second capacitive loading to generate a low-power clock signal using minimal power consumption. A compensation circuit may be used to offset a relatively high frequency error during the low-power mode.
