1-10-1993 | There is little to say about the true r.m.s. converter. The circuit diagram shows a standard application of the AD736JN, connected to a n...

1-07-1993 | The power off circuit ensures that the load is automatically removed from a battery. Itis particularly useful in cars, so that if the dri...

1-12-1992 | This circuit provides a simple means of implementing a 'soft-start' on heavy mains loads. Basically, this is achieved with the aid of hig...

1-09-1992 | Measuring a current without affecting the circuit in which that current is flowing is an ideal test method. Current-sense power MOSFETs are...

1-07-1992 | This Iittle circuit enables you to measure the so-called dynamic response of a d.c. power supply. A power MOSFET, T1, is used to switch...

1-06-1992 | A small circuit is described that inverts a positive voltage into a negative one or doubles its level. It does not use inductors and is ba...

1-05-1992 | The greater part of this month's instalment is devoted to the operation of the microprocessorcontrolled synthesizer used to tune the RF...

1-12-1991 | The power supply for the delay circuit is derived directly from the mains by a bridge rectifier; D1-D4. The rectifier must be able to han...

1-12-1991 | Amplifiers that have no capacitor at their output may, in case of a defect, apply a direct voltage to the loudspeakers and this can destr...

1-12-1991 | The emulator enables a Type 2764 EPROM in an existing circuit to be replaced by a static RAM. It is a very compact circuit: together with...
