Abstract
A system of sampling interface for an optical pick-up head comprises an optical pick-up head, a PMOS, a boost circuit, and a sample and hold circuit. The optical pick-up head outputs one of a reading voltage and a writing voltage. The PMOS gate receives the gate voltage and then the PMOS is turned on to pass the reading voltage to the sample and hold circuit. Moreover, the substrate of the PMOS receives a control voltage. The boost circuit is used to boost the gate voltage higher than the control voltage for turning off the PMOS and isolating the writing voltage.
