Here, I will elucidate the following points: What is RCWL-0516 It is yet another type of proximity motion sensor which can detect if someone has entered into an area, and raise an alarm or take an […]
Wideband Amplifier Circuits
This page discusses many types of wideband amplifier circuits. These amplifiers are utilized in a variety of high frequency applications in electronics. We’ll talk about how they operate and what makes them unique for specific RF circuit designs. A wideband amplifier is a circuit that boosts electronic signals over a wide range of frequencies, making […]
Constant Current Generator Circuits Explained
Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]
Accurate Transistor Tester Circuits Explored
In this article we talk about a few simple yet accurate transistor tester circuits which can used to identify whether a transistor is good or bad. Note: Please test *only* BJTs and MOSFETs (enhancement or depletion) with these circuits. Simple Good/Bad Transistor Checker using a Single LED Do you have a lot of strange old transistors […]
Battery Low Voltage Alarm Circuit
Despite its simplicity, the Battery Low Voltage Alarm circuit has a very important function. It forewarns you of approaching battery failure so that you may run to the store and get replacement cells before your equipment stops functioning entirely. Because of its compact size and low current need, it may be integrated into the devices […]
