A Low Noise CMOS Bandgap Voltage Reference Using Chopper Stabilization Technique
A low noise CMOS bandgap voltage reference is designed using the noise reduction technique of chopper stabilization in this paper. The mechanism of the proposed chopper technique is discussed in detail and the corresponding circuit was designed and fabricated using a high temperature and high pressure CMOS 0.18\mu m$ technology. The experimental results show that the output noise power spectral density was reduced by 60dB at 1Hz. In addition, the untrimmed voltage reference has a temperature coefficient in the −45°C to +175°C range of 43ppm/°C (mean) at a +5 V power supply.
