CMOS Gate Circuitry | Logic Gates | Electronics Textbook
A strategy for minimizing this inherent disadvantage of CMOS gate circuitry is to “buffer” the output signal with additional transistor stages, to increase the overall voltage gain of the device. This provides a faster-transitioning output voltage (high-to-low or low-to-high) for an input voltage slowly changing from one logic state to another.Mill Mountain Hike - hikingupward,Either done as a longer day hike or overnight backpack, this circuit includes Big Schloss, Mill Mountain, and Stony Creek.
