Abstract: An analog duty-cycle detector includes: off-time detection circuitry; on-time detection circuitry; compare circuitry; and a controller. The off-time detection circuitry includes a first transistor and a first capacitor. The on-time detection circuitry includes a second transistor and a second capacitor. The compare circuitry has a first terminal, a second terminal, and a third terminal. The first terminal of the compare circuitry is coupled to a first terminal of the first capacitor. The second terminal of the compare circuitry is coupled to a first terminal of the second capacitor. The controller has a first terminal and a second terminal. The first terminal of the controller coupled to a control terminal of the first transistor. The second terminal of the controller coupled to the control terminal of the second transistor.
