Abstract :
The paper present an ultra-low power NEO using full-CMOS technology based on sub-threshold analog design. The ultra-low power NEO system includes a differentiator with a differential structure and a multiplier based on the dynamic translinear principle. The circuit has been designed in 0.35μm CMOS technology and with total current consumption of about 825 nA. As is demonstrated by the simulation results, the proposed circuit has detected the instantaneous energy of the input signals well, which focus in the range from 100 Hz to 6 kHz.
