WebNov 14, 2012 · So anyway, I hope you'll forgive me for starting a new--but related--topic on this thread. It has to do with active, rather than passive, pull-up in a MOSFET circuit. On p. 317 of the Student Manual for The Art of Electronics (attached), I am instructed to construct a simple circuit in which a p-type MOSFET acts as a pull-up resistor. WebThe TTL output stage is sometimes called a totem-pole or push-pull output. Similar to the p-channel and n-channel transistors in CMOS, Q4 and Q5 provide active pull-up and pull …
WebTransistor–transistor logic (TTL) is a logic family built from bipolar junction transistors.Its name signifies that transistors perform both the logic function (the first "transistor") and … WebFor a CMOS gate operating at 15 volts of power supply voltage (V dd ), an input signal must be close to 15 volts in order to be considered “high” (1). The voltage threshold for a “low” (0) signal remains the same: near 0 volts. Disadvantages of CMOS. One decided disadvantage of CMOS is slow speed, as compared to TTL.
