Abstract
A duty cycle detector includes a current steering network configured to steer a first current into a second current to charge a first capacitor when a clock is in a first state, and to steer the first current into a third current to charge a second capacitor when the clock is in a second state; a first charge sharing switch configured to enable charge sharing between the first capacitor and a third capacitor when the clock is in the second state; a second charge sharing switch configured to enable charge sharing between the second capacitor and a fourth capacitor when the clock is in the first state; a first discharging network configured to discharge the first capacitor when the clock is in a first state; and a second discharging network configured to discharge the second capacitor when the clock is in a second state.
