Abstract

See full text

An apparatus and related method include a voltage-mode biasing network for receiving a reference current and outputting a biasing voltage, and an oscillator core for receiving the biasing voltage and sustaining an oscillation, wherein the voltage-mode biasing network comprises a current-to-voltage converter for converting the reference current into a reference voltage, a low-pass filter for filtering the reference voltage into a filtered reference voltage, and a source follower for receiving the filtered reference voltage and outputting a biasing voltage. The oscillator core comprises a resonator coupled to a regenerative network. In an embodiment, the current-to-voltage converter comprises at least a diode-connected transistor.
