Abstract
A low power crystal oscillator is provided. The crystal oscillator includes a gain stage circuit having a first gain stage input coupled at a first oscillator terminal and configured to receive a first oscillator signal of a crystal. A first bias circuit is configured to generate a first bias voltage based on the first oscillator signal. A reference circuit is configured to generate a reference current based on the first bias voltage. A comparator circuit is configured to generate a clock signal based on the first oscillator signal and the first bias voltage. The comparator circuit includes a second bias circuit configured to generate a second bias voltage. The gain stage circuit includes a second gain stage input coupled to receive the second bias voltage.
