This paper presents a CMOS voltage controlled ring oscillator (VCO) with temperature compensation circuit suitable for low-cost and low-power MEMS gas sensor. This compensated ring oscillator is dedicated to Chopper Stabilized CMOS Amplifier (CHS-A). To operate at low frequency, a control voltage generated by a CMOS bandgap reference (BGR) is described and the measurement results of the fabricated chips are presented. The output voltage of the reference is set by resistive subdivision. In order to achieve small area and low power consumption, n-well resistors are used. This design features a reference voltage of 1聽V. The chip is fabricated in AMS 0.35聽μm CMOS process with an area of 0.032聽mm2. Operating at 1.25聽V, the output frequency is within 200驴卤驴l0聽kHz over the temperature range of 驴25聽掳C to 80聽掳C with power consumption of 810聽μW. |
