  • Abstract
    A new CMOS exponential function generator is presented. The proposed circuit is compact, with low power and wide dynamic range. The proposed circuit has been fabricated in a 0.50 μm CMOS process. Experimental results show that the output range of the proposed exponential function generator can be more than 15 dB with the linear error less than ± 0.5 dB. The supply voltage is ± 1.5 V and the power dissipation is less than 0.4 mW. Experimental results are given to demonstrate the proposed circuit.
