Abstract
An apparatus comprising a transconductance control circuit, a boost control circuit, a current computation circuit and an oscillator circuit. The transconductance control circuit may be configured to generate a current control signal in response to (i) a voltage control signal and (ii) a plurality of range control signals. The boost control circuit may be configured to generate a current boost signal in response to a reference current signal and an enable signal. The current computation circuit may be configured to generate a first control signal and a second control signal in response to the current boost signal and the current control signal. The oscillator circuit may be configured to generate an output signal oscillating at a particular frequency in response to the first control signal and the second control signal.
