| Only zener diodes rated at 6 V have a negligible temperature coefficient (TC). At lower ratings, the coefficient becomes negative, and a...
| Electronic circuits must never be operated with an excessive supply voltage. Such a situation may be prevented with the protection circuit...
| The circuit in the diagram enables a negative voltage to be derived without the use of integrated circuits. Instead, it uses five n-p-n tr...
| Accurate measurements that are not affected by ambient temperature may be taken when the part or circuit being tested is placed in an oven...
| The indicator shows when the mains is present at its output by a continuous glow of a neon bulb, La1, and when the fuse is blown by flashi...
| The Type UCC3926 current sensor IC from Unitrode is ideally suited for use as a current monitor. It contains a 1.3 mΩ current shunt and...
| When r.f. signals are (to be) attenuated, it is essential that the requisite network retains correct matching to the relevant (coaxial) ca...
| Members of the 8051 family of microcontrollers (MCS51) are well-known and widely used. The controllers have a powerdown mode in which th...
| The Philbrick oscillator is a little known design, patented by the American scientist George A Philbrick in 1956. It generates signals a...
