Abstract :
This paper proposes a novel current reference circuit independent of temperature and supply variations. It uses supply-insensitive self-biasing current source as building blocks and current-mode computing circuits to compensate temperature effects. Simulation results show that the proposed current source has improved the temperature variation of the original current source with a temperature range from -50°C to 150°C at 1.5 V (+10%) power supply in a 0.12 μm CMOS process.
