So...The CMOS Circuits in Our Texts Go Back to 1963?

The first CMOS chip was created by Fairchild Semiconductor, presented at ISSCC in 1963. The logic topologies used in today’s textbooks originated in this work. P-type devices are slower than N-type by ...

Low Power Universal Gates for Approximate Computing

Density and speed of IC’s have increased exponentially for several decades, following a trend described by Moore’s Law. While it is accepted that this exponential improvement trend will end, it is ...
