For years—decades, in fact—the NMOS transistor world has been on cruise control. NMOS is naturally faster and its performance has scaled better than PMOS. PMOS has had a cost advantage. But lately, it ...

The machine is constructed from 1094 transistors, with logic in an NMOS configuration, using 10 K pullup resistors. This is not a fast way to build a circuit, but it is very compact.

By Jeremy Zelenko Even as industry moves into the era of the high k metal gate (HKMG) and FinFET transistor, chipmakers continue to seek ways to improve device performance. One of the latest advances ...

So, let’s dive right in and have a look at an NMOS and PMOS transistor, and a CMOS (“complementary,” meaning both P and N MOS transistors are in the circuit) inverter gate (Fig. 1).

Notable achievements include MoS₂ NMOS transistors with a subthreshold slope of less than 75 mV/dec and a maximum drain current of over 900 µA/µm. In comparison, WSe₂ PMOS devices achieved a ...
