Abstract
A first inverter in a clock generation circuit is coupled to an input clock signal and has multiple driver slices. Each driver slice includes first transistors that have gates coupled to the input clock signal, second transistors that have sources coupled to rails of a power supply. Each of the second transistors has a drain coupled to a source of one of the first transistors. The second transistors are turned on or turned off based on signaling state of a differential enable signal. A tuning resistor is coupled to the drains of the first transistors and further coupled to an output of the first inverter. A second inverter outputs a quadrature version of the input clock signal and has an input coupled to the output of the first inverter. A first tunable capacitor is coupled to the output of the first inverter.
