By using dual bipolar devices in one case, the manufacturer nearly perfectly matches the two devices. Although this Design Idea describes a positive power supply, you can realize a similar ...

Figure 1 shows the relevant part of the circuit for monitoring the negative rail. The circuit monitoring the positive rail replaces npn with pnp devices. Best results are obtained using inexpensive ...

The IR25750LPBF is a current sensing integrated circuit designed for MOSFET, DirectFET and IGBT current sensing. It has integrated ESD protections and eliminates external current sensing resistors.

Figure 1.1: Simplest circuit for high side sensing of positive power supplies using a PNP transistor without initial collector current. The circuit has two ranges of the monitored current selectable ...

Integrated current sensing circuits intended for Smart-Power and embedded applications featuring galvanic isolation are implemented. They are based on magnetic detection using the CMOS compatible ...

Current sensor circuit. IC CA3140 is a 4.5MHz BIMOS operational amplifier with MOSFET input and bipolar transistor output. It has gate-protected MOSFET (PMOS) transistors in the input to provide very ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

A sensing circuit is presented for a portable/handheld semiconductor based radiation sensor, which senses low current changes without the inclusion of transistor noise issues. This circuit design ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...
