Abstract: An opto-emulator transmitter includes: a current controller; an oscillator circuit; and receiver replica circuitry. The current controller has a first terminal, a second terminal, and a third terminal. The oscillator circuit has a first terminal, a second terminal, and a third terminal. The first terminal of the oscillator circuit is coupled to the second terminal of the current controller. The receiver replica circuitry has a first terminal, a second terminal, and a third terminal. The first terminal of the receiver replica circuitry is coupled to the second terminal of the oscillator circuit. The second terminal of the receiver replica circuitry is coupled to the third terminal of the oscillator circuit. The third terminal of the receiver replica circuitry is coupled to the third terminal of the current controller.

Abstract: A circuit includes a charge pump stage and a common-mode filter. The charge pump stage includes first and second transistors, and first and second capacitors. The second transistor has a first terminal coupled to a control terminal of the first transistor, has a second terminal, and has a control terminal coupled to a first terminal of the first transistor. The first capacitor is coupled between a second terminal of the first transistor and the control terminal of the first transistor. The second capacitor is coupled between the second terminal of the second transistor and the control terminal of the second transistor. The common-mode filter includes third and fourth capacitors. The third capacitor is coupled between the second terminal of the first transistor and the control terminal of the first transistor. The fourth capacitor is coupled between the third capacitor and the control terminal of the second transistor.
