What is a Complementary Transistor Pair? Complementary Transistors are a set, or "pair" of bipolar transistors that consist of one NPN and one PNP transistor which are designed to work together as part of a symmetrical circuit configuration. For bipolar transistors, the term comp...
Voltage Biased Clamping Circuits A Biased Clamper Circuit allows for an input waveform to be shifted above or below a DC reference level other than 0V without distorting the waveform. We saw previously in our Diode Clamping Circuit tutorial that a diode clamper is basically a wav...
What Is A Clamping Diode And How Does It Work? A Diode Clamping Circuit is an electronic circuit configuration which can be used to change the DC voltage level of an input waveform. Unlike diode clipper circuits, or voltage limiter circuits, a clamping circuit does not change the...
Creating Logic Gates using Transistors Building logic gates using transistors is extremely easy to understand and a great way for the electronics beginner to learn more about logical switching functions. There are, of course, many different ways we can create individual logic gat...
Introduction to the Instrumentation Amplifier The instrumentation amplifier, (INA) is another type of operational amplifier circuit consisting of two or more op-amps connected together to provide a very high impedance at both of its two input terminals. Electrical output signals ...
What is the Identity Law in Boolean Algebra? The identity law in mathematics states that special numbers such as: Zero, (0) and One, (1) do not change the value of another number when combined with it using specific mathematical operations. These special "identities" act like neu...
What is a Phototransistor The Phototransistor is another light-sensitive optoelectronic semiconductor device that conducts current when exposed to light. The phototransistor functions just like a standard bipolar transistor, but instead of using a base current, it uses incident l...
What is Negative Temperature Coefficient? Negative Temperature Coefficient, or NTC for short, plays an important role in determining the thermal behaviour of various electrical and electronic components. Such as thermistors, amplifiers and semiconductors. There are multiple types...
