Abstract
A circuit and method thereof for sampling/holding signal is provided. The signal sampling/holding circuit comprises a first signal sampling/holding device, a second signal sampling/holding device, a target signal and a reference voltage. First, the first signal sampling/holding device is supplied with the reference voltage and the target signal. The reference voltage is disconnected from the first signal sampling/holding device before the target signal is. Similarly, the reference voltage is disconnected from the second signal sampling/holding device before the target signal is. Thus the target signal is respectively sampled and held in the first signal sampling/holding device and the second signal sampling/holding device.
