A clock generation circuit coupled to an integrator circuit uses a variable resistance that is adjusted in a transconductance bias feedback circuit. This resistance is calibrated to the reciprocal of the transconductance of the input amplifier. The product of the adjusted resistance and a capacitance in the clock generation circuit provides a time constant for the settling time of the integrator and controls a pulse width of an adaptively controlled duty cycle output clock.
