Simulation Results

A low temperature coefficient, high voltage detection circuit used in Power over Ethernet is proposed. This circuit realizes the detection comparison without utilizing an extra voltage reference circuit and comparator while the temperature coefficient of the threshold voltage is as low as that of a regular bandgap reference. The proposed detection circuit is implemented in CSMC 0.5μm 60V BCD process, Cadence Spectre simulation results show that the temperature coefficient of the threshold voltage is 66.5 ppm/°C over the temperature range of -40°C to 125°C, and the maximum variation of the threshold voltage is 2.7% under all corners.

Simulation Results

This paper presents a design and analysis method of a bandgap reference circuit. The Bandgap design is realized through the 0.18um CMOS process. Simulation results show that the bandgap circuit outputs 1.239V in the typical operation condition. The variance rate of output voltage is 0.016mV/°C? with the operating temperature varying from-60°C? to 160°C?. And it is 3.27mV/V with the power supply changes from 1.8V to 3.3V.
