Bipolar junction transistors (BJTS) can be turned on or off by base current. However, because the voltage drop at both ends of the base-emitter diode is largely temperature-dependent, a series resistor is required in many applications to keep the base current at the desired level, thus ensuring that the BJT operates stably and safely. Read this article to learn how to use RET to cope with the temperature dependence of standard BJTS.

Electronic engineers and technicians are accustomed to seeing noise as a negative factor and therefore optimize for low noise during component selection, circuit design, and circuit board layout. In fact, random or pseudo-random noise can sometimes be useful. This article will further explain why and how to use noise.

We live in an age of being wrapped in electronic devices that make learning, working, exercising, traveling and communicating very convenient, and wearables in particular are becoming an integral part of People's Daily lives. In medical applications, wearables can be used to monitor heart rate, blood pressure, blood oxygen levels, calories burned during exercise, sleep tracking and more. To provide a better user experience, high performance, small size and low power consumption are key metrics for these wearables

The market demand for industrial applications is increasing day by day, and data acquisition system is the key equipment. They are usually used to detect temperature, flow, liquid level, pressure and other physical quantities, and then convert the analog signals corresponding to these physical quantities into high-resolution digital information, which is then further processed by software.

Parasitic inductance refers to the inductance parasitic on the PCB wiring or other components of the circuit board. Generally speaking, there will be a parasitic inductance where there is a wire, such as the copper wire on PCB, through the hole, even the bonding wire inside the chip will have a certain amount of parasitic inductance, the inductance of these parasitic inductors is generally from a few nH to dozens of nH.

What is the chip? A "chip" is a small piece of silicon containing an integrated circuit, often part of a computer or other electronic device. A chip, or microcircuit, microchip, or integrated circuit, in electronics is a way of miniaturizing a circuit (mainly a semiconductor device, but also a passive component, etc.), usually on the surface of a semiconductor wafer.

Whether in buildings or in production workshops, programmable controllers are needed everywhere today to regulate various processes, machines and systems. This involves the PLC or DCS modules to which the equipment is connected. To control these devices, PLC and DCS modules usually have output modules with current output, voltage output or a combination of both.
