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.

Reference Circuit

In this paper, an all CMOS current reference circuit which generates a reference current independent of PVT (Process, supply Voltage, and Temperature) variations is presented. The circuit consists of a self-biased current source (SBCS) and two nested connected transistors which supply a voltage with positive temperature coefficient and the resulting reference circuit has low temperature coefficient. It is based on CSMC 0.5um mixed-signal process with the supply voltage of 5V. The precision of reference current is about ±3.05% when considering the process, supply voltage and temperature variation at the same time.

Reference Voltage Source

A bandgap reference voltage source with a temperature coefficient adjustment block was proposed. The bandgap topology employs current summation and the circuit was designed through metaheuristic algorithms in a 0.35-mm CMOS technology. Simulations with typical parameters show that the designed circuit has temperature coefficient of 15 ppm/0C, line regulation of 263 ppm/V, and current consumption of 2.71 uA in 1.0 V power supply. An additional 3-bit temperature adjustment block allowed keeping the temperature coefficient values lower than 26.6 ppm/0C for 90% of the circuits, without interfering with the reference voltage output or line regulation values.
