Design of a Reference Voltage Source Based on Complementary Threshold Voltage of NMOS and PMOS
並列摘要
A new reference voltage source is presented according to the linear relationship between temperature and the threshold voltages of NMOS and PMOS. Compared with ordinary CMOS band‐gap reference, the designed circuit doesn't need parasitic transistor, and the process parameters are easier to control. In addition, the output reference voltage has a theoretical zero temperature coefficient at any point within circuit normal operating temperature range, and its value can be arbitrarily adjusted. The simulation results indicate that the circuit has better temperature stability and high power supply rejection ratio.
