摘要:
A temperature sensing device is disclosed which utilizes a temperature sensing circuit which generates a voltage whose level varies linearly in accordance with temperature, this voltage being produced using a pair of MOS field effect transistors which have different values of the ratio Id/K, where Id is drain current and K is the channel pattern ratio of channel width to channel length.
