Abstract :
A micropower CMOS voltage-to-current converter is introduced which has a widely linear differential-input swing with a low signal-distortion with a minimum supply voltage of 1.2 V. This proposed circuit can achieve an almost rail-to-rail differential-input swing with at least 1.5 V supply-voltage. The proposed circuit uses class-AB linearisation to achieve widely linear input-swing in the saturation region. In a 1.2 μm n-well CMOS process, the 3 dB frequency of the V-I converter is in a range of 44 M-57 MHz with different biases at the supply voltage of 1.5 V. High frequency capability (⩾100 MHz) can be easily realized with higher supply voltages of 2 V, 3 V. The total power consumption is around 1.5 μW at the minimum supply voltage of 1.2 V
