摘要： The pudo resistance circuit and the charge detection circuit are compod of a first field effect transistor (Ma), a cond field effect transistor (Mb) of an electrical characteristic matched with the electrical characteristic thereof, and a cond resistance element A voltage divider circuit (21) having one end connected to the source terminal of the cond field effect transistor and a source terminal of the cond field effect transistor connected to the gate terminal of the first field effect transistor and the gate terminal of the cond field effect transistor , A first operational amplifier (OP1) to which the midpoint voltage of the voltage dividing circuit is input to corresponding one of the inverting input terminal and the non-inverting input terminal and the reference voltage is input to the corresponding other of the inverting input terminal and the non-inverting input terminal, And a cond operational amplifier (OP 2) for inputting a voltage obtained by inverting and amplifying the drain voltage of the first field effect transistor at the other end of the element.
