www.radioman33.comIn this Transistor Circuits ebook, we have presented about 100 interesting circuits using transistors and chips. In most cases the IC will contain 10 - 100 transistors, cost less than the individual components and take up much less board-space. They also save a lot of circuit designing and quite often consume less current than discrete components.

Drive circuits for Power MOSFETs and IGBTs
www.st.comDRIVE CIRCUITS FOR POWER MOSFETs AND IGBTs by B. Maurice, L. Wuidart 1. INTRODUCTION Unlike the bipolar transistor, which is current driven, Power MOSFETs, with their insulated gates, are voltage driven. A basic knowledge of the principles of driving the gates of these devices will allow the designer to speed up or slow down the switching
Designing Digital Circuits a modern approach
www.arl.wustl.eduSo how is it that digital circuits have become such a big deal in such a short time? There are two key inventions that have driven the digital revolution. The rst was the invention of the transistor in the late 1940s, and the second was the invention of the integrated circuit in the late 1950s. 11

Chapter 9: FET Amplifiers And Switching Circuits
staff-old.najah.eduSwitching Circuits 9-1: The Common Source Amplifier (CS Amplifier) FET has an important advantage compared to the BJT due to the FET’s extremely high input impedance. Disadvantages, however, include higher distortion and lower gain. The common-source (CS) amplifier iscomparable to the common-emitter BJT amplifier that you studied in Chapter 6.
