Approaches to the implementation of compensations for temperature drift and offset voltage of a device are given in this paper. Also presented are considerations on the structural design of the circuit, selection of process parameters and the layout design. Experimental results show that a temperature drift equal to or less than 0.2%℃ and an offset voltage drift of 100～200 mV for an actual derice, which meet the requirements for applications, have been achieved through the compensation designing.
