Abstract :
A CMOS current reference circuit is presented, which can work properly with a supply voltage higher than 1 V. By compensating the temperature performance of the resistor, this circuit gives out a current with a temperature coefficient of 50 ppm/°C over the temperature range of (0°C, 110°C) and a 0.5% variation for a supply voltage of 1 to 2.3 V.
