Diode transistor logic not gate . As shown in fig. You need an amplifier of some kind. 32 the diodes d1 and d2 perform the and operation. The dl gate with the addition of one transistor is called as the dtl diode transistor logic gate. To ensure proper operation of the circuit a diode d3 is also added as shown in fig. For the not logic there is only one transistor and the output is driven to the ground low or 0 if it is conducting. A not gate needs to be able to change a 0 to a 1 a...
