Abstract
An example apparatus includes: a receiver operable to receive a modulated input signal at a receiver input and output a demodulated signal at a receiver output, the receiver comprising a switch having a first current terminal and a first control terminal, the first current terminal coupled to the receiver output. The example apparatus includes a capacitor having a first terminal and a second terminal, the second terminal coupled to the first control terminal and the first terminal coupled to the receiver input. The example apparatus includes a resistor having a third terminal and a fourth terminal, the fourth terminal coupled to the first control terminal. The example apparatus includes a voltage offset source having an input and an output, the output coupled to the third terminal. The example apparatus includes a current source coupled to the first current terminal.
