An additional function usually performed, though not logical in nature but nevertheless a practical necessity, is signal amplification.When the base-emitter diode is turned on enough to be driven into saturation, .Logic gates are constructed from so-called “transistors”. On the input terminals, we provide a digital signal and on the output terminal, it provides a digital output. Transistor–transistor logic (TTL)is now an outdated bipolar technology in which one or more transistors are driven into a highly saturated state so that excess charge is injected into the base region of the transistors.
A basic circuit using any general-purpose bipolar transistor such as the BC549, BC548, or BC547, could be used to construct the gate.
