ゲート電圧制御を考慮した微小電源電圧駆動PTAT電圧発生回路における温度係数の一考察

抄録

A way of large temperature coefficient on PTAT voltage generator is proposed. By stacking the proposed circuits, a PTAT voltage generator with large temperature coefficient can be realized. The PTAT voltage generator is analyzed by use of 4-terminal MOSFET model in subthreshold region based on the diffusion current. The temperature coefficient of measured value is compared with that of theoretical value.
