Abstract
A quantizer takes an analog signal as input and produces a quantized signal for output. The quantizer includes a shoot-through current detection unit and a feedback unit. The shoot-through current detection unit is configured to detect a shoot-through current flowing through the quantizer. The feedback unit is configured to feed back a signal from the shoot-through current detection unit and control an electric charge stored at an input of the quantizer.
