Abstract
This paper presents a fully integrated digitally controlled CMOS voltage amplifier. Operating at 3.3 V, this three-stage amplifier was designed and fabricated in an Austriamicrosystems (AMS) 0.35 µm process technology. The amplifier does not require any external discrete components to function and its gain value can be configured by providing digital signals to its control pins. The amplifier performs AC-coupling on the input signals to ensure suitable biasing for proper operation. The good stability of the circuit has been verified. Results obtained from simulations and experiments show that the circuit has a minimum bandwidth of 17.2 MHz. The circuit has been proven to execute well for the gain settings of ×1, ×10, ×100 and ×1000 with acceptable losses of 0, −2, −5, −12 dB respectively.
