Hybrid Voltage and Current References Based on Double ZTC Points

A novel design idea, based on the double zero temperature coefficient (DZTC) points, for voltage and current references with temperature and power-supply independency is proposed. A circuit topology is developed for realization of this idea. It does not only provide two voltage references, but also give one current reference, simultaneously. Furthermore, the circuit is very suitable for mixed-signal, VLSI, and SOC design, because only pure MOSFET transistors are used. The simulation results by using 0.35-μm CMOS technology show the DZTC voltage and current references with very good temperature performance, comparing with previous works.
