In the following paper, there is a presentation of a small potential, small capacity CMOS which programs numerically working trans conductance circuit of an amplifier (OTA). A constant transconductance up to (7% of max variation) secures the whole usual-mode of the input range. The circuit process and it can also be operated on a voltage supply of 3.3V with a common-mode range of input from 0.3 to 1.6V. A constant-current is maintained by the designed OTA and also provide a continuous transmission capacity for varying burden capacitors with no increase in consumption of capacity. Simulation of the circuit works upon T-SPICE .5 µm level 49 sub-micron technology.
