A system for quantizing an analog signal comprises a first negative-resistance device. The first negative-resistance device has a first terminal coupled through a capacitor to receive a clock signal and a second terminal coupled to receive an analog input signal. A second negative-resistance device has a first terminal coupled to receive the input signal and a second terminal coupled through a capacitor to receive an inverted clock signal. An output terminal is coupled to the second terminal of the first negative-resistance device and the first terminal of the second negative-resistance device. A quantized output signal is generated at the output terminal.
