The History Of CMOS

Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. Before CMOS, there was NMOS (also PMOS, but I have ...

Power dissipation in portables: Design considerations using low-power CMOS ICs

When a CMOS circuit is in an idle state there is still some static power dissipation–a result of leakage current through nominally off transistors. Both nMOS and pMOS transistors used in CMOS logic ...

Models for high-voltage transistors in a standard CMOS process

Designers of electronics and communications systems are constantly faced with the challenge of integrating greater functionality on less silicon area. Many of the system blocks – such as power ...

Breakthrough Pseudo CMOS Transistors for 1000 Times More Efficient Computing

As transistors are scaled to smaller dimensions, their static power increases. Combining two-dimensional (2D) channel materials with complementary metal–oxide–semiconductor (CMOS) logic architectures ...

A Review Paper on CMOS, SOI and FinFET Technology

In 1958, the first integrated circuit flip-flop was built using two transistors at Texas Instruments. The chips of today contain more than 1 billion transistors. The memory that could once support an ...

Voltage Translation From NMOS Switches

Pericom’s PI5Cxx switches can be used for voltage translation and also for hot-swap applications. This app note discusses the use of Pericom’s switches in 5V to 3.3V, 5V to 2.5V and 3.3V to 2.5V ...

The Good Kind Of Bias

Back gating, body bias, substrate bias, and back bias all refer to a technique for dynamically adjusting the threshold voltage of a CMOS transistor. CMOS transistors are often thought of as ...
