In this post we introduce simple and flexible, regulated low voltage power supply unit. This power supply has provision for 4 outputs such as 1.5V, 1.8V, 2.5V and 3.3V. We mainly build this low voltage power supply unit to test (and power-up) low voltage MCUs, CPLDs and radio receivers. For this power supply we choose

Iāve been spending a lot of time thinking about op amps and comparators lately. One of the common uses of an op amp is as a āunity gainā buffer, meaning that the output voltage is as close as possible to being the same as the input voltage. At a glance this might seem like a

The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the
Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a multiturn pot) would offer improved control over the varactor voltage. However, this approach still didn’t

Voltage suppressors are used to protect circuits from unwanted transients, when other devices like diodes and capacitors fail to do so. Transient effects have various sources and are able to damage the connected parts and ICs if not properly measures taken. In this article we will discuss about the various transient voltage suppressors and their
