摘要：

Human body implants, portable electronic gadgets and a number of distributed sensor network applications required low power as well as low energy consuming electronic circuits. Most of such electronic circuits need analog to digital converters also. In this paper the authors are proposed a design of the level crossing analog to digital converter (LC-ADC) architecture. The proposed circuit has been implemented in UMC 180 nm technology and its performance was evaluated using cadence virtuoso at supply voltage 0.8 V. The simulation results have been presented. The propose ADC consumes 62 nW-106nW power in the frequency range 5 Hz-3.3 kHz.
