A simple inverted amplifier circuit design
Inverted amplifier circuit design A reverse amplifier circuit: the output signal is in opposite phase to the input signal and the voltage or current value is proportional. The diagram below …
Differential Amplifier Principle Explained
Differential Amplifiers Differential amplifiers are different from ordinary op-amps in that they do not require an external resistor to form a differential amplifier circuit, which amplifies the difference between two …
DC bias control using op-amps to build decimation circuits
Controlling DC Bias Circuits This article is about using op-amps to build a subtractive circuit to control DC bias. Since the vast majority of ADCs are unipolar, the signal needs …
A simple differential amplifier circuit design
Differential amplifier circuits (subtractors) A differential amplifier is generally used to input multiple signals and output the difference between them. It is often used to amplify differential mode signals and …
Analysis of a typical amplification application circuit of a triode (I)
Today more and more switching circuits are being replaced by MOSFETs in triode application circuits. Field effect transistors (FETs) are voltage controlled devices that are simple to drive, fast and …
LT8582 dual channel converter in a monolithic dual channel solution
There is no shortage of ICs available to help designers build switching DC/DC switching power supplies. Options range from multifunction controllers requiring multiple external components to fully integrated monolithic solutions …
Analysis and application of 4 common constant current source circuits
A basic constant current source circuit consists mainly of an input stage which provides the reference current and an output stage which outputs the required constant current. The constant current …
First order low pass filter (LPF) learning
Introduction: Voltage-based chain observers are of interest because of their clear physical concept and simplicity of use. However, the voltage chain observer contains a pure integral term, and the initial …
Bridge, phase shift and double-T RC oscillation circuits are commonly used to generate sinusoidal signals
I think we are not unfamiliar with the signal “sine wave”, but as for how to generate it, we may not know much about it. There are many circuits to …
Why is a MOS tube connected in parallel with a diode? What is the purpose?
MOS tube, an abbreviation for MOSFET, the full spelling is Metal-Oxide-SemiconductorField-Effect Transistor, translated as Metal-Oxide-Semiconductor Field-Effect Transistor, depending on the conductive channel, MOS can be subdivided into two types of …
