Abstract: A clock signal conversion circuit includes an amplification circuit configured to amplify a differential clock signal having sub rail-to-rail voltage swings relative to a supply voltage, such that an amplified differential clock signal output by the amplification circuit has complementary positive and negative signal components with full rail-to-rail voltage swings relative to the supply voltage. A duty cycle distortion correction circuit includes: a filter having a cutoff frequency below the frequency of the differential clock signal and configured to output a differential voltage that is proportional to a difference in duty cycle between the positive and negative signal components of the amplified differential clock signal; and a transconductance amplifier configured to convert the differential voltage to a differential current that is provided to the amplification circuit as feedback for reducing the duty cycle difference between the positive and negative signal components of the amplified differential clock signal.
