Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...
See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...
