Abstract
Circuitry for providing an oscillating output signal. The circuitry comprises a transconductance circuit having a first input, a second input, and an output. The circuitry further comprises an oscillator circuit coupled to receive voltage from the output of the transconductance circuit, wherein the oscillating output signal is responsive to an output of the oscillator circuit. Also included are circuitry for providing a first voltage to the first input of the transconductance circuit and a frequency controlled circuit for providing a second voltage to the second input the transconductance circuit. The second voltage is response to a frequency of operation of the frequency controlled circuit, and the frequency of operation of the frequency controlled circuit is responsive to feedback from the output of the oscillator circuit.
