Summary

The proposed circuit is a Digitally Programmable Gain Amplifier (DVGA) which will work to amplify voltage signal with programmable gain options, ranging from 1 V / V to 256 V / V. The main core is an OTA Miller with output buffer configured as an inverter amplifier. The circuit feedback resistances is controlled by 8 CMOS switches (Transmission Gates) that are configured according to binary word stored in the shift register which is connected to a Serial Peripheral Interface (SPI) that provides a connection for external control.
