Abstract

The main component of Analog to Digital Converter (ADC) Single Slope type is an Analog Unit. The analog unit is designed precisely to meet characteristics of the ADC. The ADC design has a resolution of 8 bits and frequency clock of 1 MHz . Openloop amplification of OpAmp is 66.42 dB. Set point voltage comparator at the level of 1.65 V. The value of RC in the circuit integrator = 16 . The reference voltage used is 2 volts, so that the LSB value obtained is 0,125V. Sample and hold level is designed for 1 µs with a 31.25ns pulse width, resulting in a single enumeration there will be pulse of 16 x 62.5 ns clock. Method of research is done by simulation using mentor graphic with 0,35 AMS technology. The result is an analog unit design of Single-Slope ADC with a speed of 1 us and maximum of reference voltage is 2 Volt and it is able to give amplitudes sampling up to 0.02 Volt
