A Single‐Stage Differential Amplifier Using Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
A three‐transistor differential amplifier using depletion‐mode organic electrochemical transistors is implemented that offers a common‐mode rejection ratio of up to ≈20 dB. Compared to a Wheatstone bridge amplifier, ECG recordings with this amplifier showed improved signal‐to‐noise ratio, gain, and power consumption.
