The XOR output is therefore high. If the pin-4 input is now driven high, the XOR gate responds immediately by driving its output low. But after the delay circuit responds (about 15ns in this case), ...

So, with zero input current, both Q1 and Q3 conduct Ibias, as does Q2 and Q4 and the circuit acts with a differential output. Figure 3 LTspice simulation of differential output in response to small ...

A central goal of synthetic biology is to create cellular networks that integrate input signals for decision making and actuation 1.In recent years, artificial logic gates 2,3,4 and memory devices ...

The internal circuit of a single 7400 dual-input NAND gate. 30px MovGP0 (CC BY 2.0 DE). ... The 7400 didn’t have ESD protection diodes on the output (or input for that matter).

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of ...

Thus, the output frequency varies by approximately ±64.5 kHz around 106 kHz for an input change of ±100 mV from 0 V. This circuit's accuracy is better than 0.2% of full scale.
