摘要

The circuit device (10) has a FET (12) whose source electrode (17) is connected with a reference potential (14). A drain electrode (18) and a gate electrode (15) of the FET are respectively connected with a read element (11) and a drive circuit (24). The drive circuit is provided with a driver circuitry (19) and an eliminating circuitry (23) that are connected with each other. A controlled current path (27) is connected between the gate electrode and reference potential.
