Abstract: A circuit includes a first device between a first input node and an internal node, a second device between a second input node and the internal node, a third device between the internal node and ground, a fourth device between the internal node and an output node, and a fifth device between the output node and ground. The second and third devices generate a direct current (DC) voltage on the internal node by dividing a bias voltage on the second input node. The fourth device generates, from the DC voltage, a first component of an output voltage on the output node. The first and third devices generate a modulation signal on the internal node by dividing a radio frequency (RF) signal on the first input node. The fifth device rectifies the modulation signal to generate a second output voltage component.
