Abstract :
A new idea is proposed to make use of the disadvantages at low-voltage operations to widen the output dynamic range and the input swing of the exponential voltage-to-voltage circuit with differential input, at low-voltage low-power applications. The pseudo-exponential function is used to realise the exponential characteristic. Based on 0.25 μm CMOS technology, simulations show a 16 dB linear improvement of the output voltage range while dissipating less than 0.2 mW from 1.25 V supply voltage.
