Photoconductivity - Definition, Working and its Applications: Photoconductivity - When excess electrons and holes are produced in a semiconductor, there is a corresponding increase in conductivity of a sample as…
Luminescence - Definition and Types: When a system absorbs energy in some form or other, it may be partly re-emitted as radiation. This phenomenon is called luminescence. Luminescence may occur…
Miller Sweep Circuit and Miller Bootstrap Sweep Circuit: The basic R-C sweep circuit is shown in Fig. 30.134, in which opening of switch S provides sweep voltage, as already explained…
Time Base Generator - Working Principle and Types: Time base is an axis, normally X-axis, that is used to represent time so that variations of quantities such as voltages, currents…
Peak to Peak Detector - Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal.…
Diode Clamping Circuit - Positive and Negative Clamping: Diode Clamping Circuit - A circuit that places either the +ve or -ve peak of a signal at a desired level is…
Diode Clipping Circuit - Types and Applications: Diode Clipping Circuit - For a clipping circuit at least two components—an ideal diode and resistor are required and sometimes a dc battery…
What is Current Conveyors (CCs)? Current conveyors (CCs) were first introduced by Smith and Sedra and have been used in a variety of electronic applications. The CC is a three-port…
