چکیده
A low-voltage low-power analog CMOS exponential function generator is designed in 0.18μm CMOS standard technology. The proposed circuit uses Taylor’s approximation concept and consists of a linear low-voltage transconductance with two linearization techniques and one low-voltage current squarer circuit for performing this approximation method. Simulation results using HSPICE shows 60 dB-linear output current range with the linearity error less than ± 0.5 dB. The total power consumption is below 0.14mW with a single 1 V power supply.
