| This simple circuit is designed for use with all kinds of DC motors up to 40 amps. Basically it’s just a simple oscillator driving a bunch o...
| A nanopower op amp, a low-threshold P-channel MOSFET, and two feedback resistors are combined to make a rectifier circuit with less forward...
| Cutting the power rapidly in the event of an overload implies monitoring the current through the load. This is usually done either by measur...
| While building a single-ended class A MOSFET amplifier consisting of two mono blocks, this designer did not want to use a coupling capacitor...
| In last month’s column I discussed a MOSFET that allows the current through the FET to be measured efficiently. This time I will deal with a...
| In this month's instalment and the next we will take a look at MOSFETs with unusual characteristics. Because quite a lot can be said about t...
| The unit described here enables you to test NPN and PNP bipolar transistors, N- or P-channel FETs or MOSFETs, UJTs, triacs, and thyristors....
| Good old electromechanical relays are relatively expensive where any significant current has to be switched and switching times must be shor...
| For load currents up to 4 A the author has used a bistable relay to disconnect the load on a 12 V battery to avoid deep-discharge. How can w...
