A discrete-time amplifier based on Thin-Film Trans-Capacitors for organic sensor frontends

The high sensitivity of organic materials to many different physical quantities makes smart sensors one of the most appealing applications for organic electronics. In this paper we deal with the design of a new device, a Thin-Film Trans-Capacitor, that can be employed to design discrete-time amplifiers for sensor frontends. Simulations of the circuit proposed show that the gain of the sensor frontend increases of about one decade without any detrimental effect on the speed. CAD (Computer-Aided Design) simulations confirm the results of the simple mathematical model we present.
