-multiplier combined with a metal resistor for temperature compensation and utilizes digital resistor trimming for TC and output current calibration. The circuit has been designed at the transistor level and extensively simulated in a 180-nm BiCMOS process. Simulation results show less than 1% corner and mismatch variation of the nominal 10-μA output current and a remarkably low 11.3-ppm/°C residual temperature coefficient over the range from -40 to 135 °C. |
