The output of the first stage (i=1) XOR logic, A B, is connected to the gate of the CMOS-based pair of pass transistors labelled (3, 3) to decide whether to pass input B (A also works here) or ...

Figure 1 The XOR logic element and its analog using discrete elements.. The second variant of the 2XOR element is shown in Figure 2.Transistors Q1 and Q2, as well as resistor R2, serve as the 2AND ...

The 10-kΩresistor cannot provide this current.However, using the previousXNOR configuration and anotherinverting transistor after Y, you canobtain the XOR function (Figure1b). The XOR seems to be ...
