|Flexible Organic CMOS|
CMOS technology, which requires the use of complementary pairs of n-type and p-type transistors to construct integrated circuits, has been widely used to manufacture digital and analog devices.
A CMOS (complementary metal oxide semiconductor) inverter. When positive voltage is applied, the n-type transistor is pulled on, and the output is pulled to the source voltage. When the gate is off at 0V, the p-type transistor is on, and the output is grounded to 0V.
CMOS devices have two important characteristics: high noise immunity and low static power consumption. CMOS devices will draw significant power only when the transistors are switching between on and off states. As a result, CMOS devices do not produce as much heat as other forms of logic, for example transistor-transistor logic (TTL) or NMOS logic, which uses all n-channel devices without p-channel devices. CMOS also allows a high density of logic functions on a chip.
Historically, CMOS had not been possible in the area of printed and flexible electronics, because only p-type organic semiconductors had shown the requisite level of performance. With the advent of Polyera's ActivInk™ n-type organic semiconductors, CMOS circuits are now possible for the first time, leading to simpler circuit design and lower device power consumption.
