Abstract
PURPOSE: To ensure the temperature compensation for the analog quantity at the reading time by applying the gate voltage of the floating gate type MOSFET which is to be an analog memory via the MOSFET featuring the same characteristics at the floating gate type MOSFET.
CONSTITUTION: The accumulated analog quantity varies by the reading gate voltage, and accordingly the reading voltage is varied in accordance with the temperature drift. This reading voltage is obtained from the output of MOSFET(T) which is cascade-connected to memory FET. In other words, both the gate voltage applied to MOSFET(T) and the characteristics of the drain current function in the direction where the temperature drift of the memory FET is offset. As a result, the temperature is compensated at the reading time of the analog quantity.
