Operational Transconductance Amplifier (OTA): The operational amplifiers considered up to this point have been voltage amplifiers. The input signal is a voltage and the output signal is a voltage. Another…
What is Current Foldback? The current limiting technique maintains a constant load current at some specified value and under overload condition, the Vout drops to zero. But, in case of…
Op Amp Regulators: The Op Amp Regulators which includes Op-Amp Series Voltage Regulator Circuit, Current Limiting circuit, Foldback Limiting and Op-Amp Shunt Voltage Regulator Circuit. Let us see one by…
Comparison of Logic Families: The following are the Comparison of Logic Families are 1. RTL and DTL families have become obsolete because of their low speed, high power dissipation, and…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are…
PN Junction Diode Applications: An ideal PN Junction Diode Applications is a two terminal polarity sensitive device that has zero resistance (i.e., diode conducts) when it is forward biased and…
Series Diode Configurations with DC Inputs: The approximate models discussed in preceding section are used for investigation of a number of series diode configurations with dc inputs. This establishes a…
