) circuit is described. The temperature coefficient of 5 μV/℃(T=-60～+100℃) and V_

sensitivity of 0.1 mV/V(V_

=3～5V) are achieved with a standard CMOS process. The combination of current modes of n-MOSFETs, which are subthreshold, linear and saturation current mode, can provide small voltage and temperature dependence. Three different regions in I-V characteristics of MOSFETs generate a constant V_

based on threshold voltage at 0 K. A feedback scheme from the reference output to gates of n-MOSFETs extremely stabilizes the output. The circuit has been fabricated in a 1.2μm n-well CMOS process and its die area is 0.18mm^2.
