An all-CMOS circuit for combined voltage reference and temperature sensor is proposed. For voltage reference design, a self-PTAT current is generated for compensating a diode-connected NMOS transistor for achieving temperature-independent purpose. In addition, an ultra linear temperature sensor can be realized and achieved simultaneously. The circuit topology is very suitable for SoC integration. The voltage reference provides a stable voltage for analog circuit. Moreover, the temperature… CONTINUE READING
