Abstract
The present invention relates to a novel and inventive compound device structure, enabling a charge-based approach that takes advantage of sub-threshold operation, for designing analog CMOS circuits. In particular, the present invention relates to a solid state device based on a complementary pair of n-type and p-type current field-effect transistors, each of which has two control ports, namely a low impedance port and gate control port, while a conventional solid state device has one control port, namely gate control port. This novel solid state device provides various improvement over the conventional devices.
