WebBiasing Transistor Switching Circuits: Direct-Coupled Switching Circuit – When a transistor is used as a Biasing Transistor Switching Circuits, it is either biased off to I C = 0, or biased on to its maximum collector current level. Figure 5-53 illustrates the two conditions. Note that the circuit in Fig, 5-53 is termed a direct-coupled switching circuit, because … In electronics, direct coupling or DC coupling (also called conductive coupling and galvanic coupling) is the transfer of electrical energy by means of physical contact via a conductive medium, in contrast to inductive coupling and capacitive coupling. It is a way of interconnecting two circuits such that, in addition to … See more The provision of DC bias only occurs in a group of circuits that forms a single unit, such as an op-amp. Here the internal units or portions of the op-amp (like the input stage, voltage gain stage, and output stage) will be direct … See more The advantage of direct coupling is very good low frequency response, often from DC to the highest operating frequency that the system will allow. All applications that require monitoring of slowly changing signals (such as those from thermistors, thermocouples See more • Common Impedance Coupling See more This technique is used by default in circuits like IC op-amps, since large coupling capacitors cannot be fabricated on-chip. That said, … See more One advantage or disadvantage (depending on application) of direct coupling is that any DC at the input appears as a valid … See more • Direct-coupled amplifier • Electromagnetic compatibility • Electromagnetic interference • Galvanic isolation • Ohmic contact See more javascript framework for mobile apps
