Transfer Characteristics

We know that for a bipolar junction transistor (BJT), the output collector current IC and the control input base current IB are related by the parameter beta, which is assumed to be constant for an analysis. Referring to the equation below, we find a linear relationship existing between IC and IB. If we make the … Read moreTransfer Characteristics

MOSFET (Enhancement-Type)

Although depletion type and enhancement type MOSFETs look similar with their internal structures and functional mode, their characteristics may be quite different. The main difference being the drain current which depends on a specific level of gate-to-source voltage for the cut off action. Precisely, for an n-channel enhancement-type MOSFET a positive gate/source voltage effects its … Read moreMOSFET (Enhancement-Type)

P-Channel MOSFET in H-Bridge Applications

Introduction P-channel MOSFETs are usually implemented for load ON/OFF switching. The ease-of-use of P-channel options on the high side allows them to be very convenient for applications like Low-Voltage Drives (H-Bridge Networks) and non-isolated Point of Loads (Buck Converters) and in applications in which space is a critical limitation. The key benefit of a P-channel … Read moreP-Channel MOSFET in H-Bridge Applications

MOSFET (Depletion-Type)

Two main types of FETs that presently exist are: JFETs and MOSFETs. MOSFETs can be further classified into depletion type and enhancement type. Both these types define the fundamental mode of operation of MOSFETs, while the term MOSFET itself is the abbreviation of metal-oxide-semiconductor-field-effect transistor. Due to the fact that the two types have different … Read moreMOSFET (Depletion-Type)
