Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

A layout-dependent circuit-design model from Toshiba helps boost gate density and improve cost-performance in next-generation 45-nm CMOS technology. More specifically, 45-nm CMOS gate density can be 2 ...

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 ...

Any typical digital design style with CMOS uses complementary pairs of p-type and n-type MOSFETs for logic functions implementation. Naturally, CMOS always ought to provide INVERTED outputs like ...

This CMOS two-input combination NAND/NOR gate is a three-input, fourpin logic gate. A p-channel enhancementtype MOSFET (Q1) and an n-channel enhancement-type MOSFET (Q4) form one complementary ...

The three main logic families in the 1980s were TTL, ECL, and CMOS. The three main logic families in the 1980s were TTL, ECL, and CMOS. In my previous column, we started our look at logic data sheets ...
