When you design a transformer for any power converter, you face several compromises. You must trade off core size against the number of primary turns and flux density. Another trade-off is the number of turns and winding resistance versus the ...
Many designs exist for logic-based astable multivibrators, one of the simplest being an RC feedback loop around a single inverting Schmitt trigger inverter (Figure 1). The output charges the capacitor to the upper switching threshold, at which ...
Why not take advantage of the micro-controller included in many systems these days? This design uses microcontroller feedback to produce a 50-V, 1-W power supply (see Figure 1). It leverages an unused analog-to-digital converter (ADC) input and a ...
A previous Design Idea describes a simple way to automatically turn off a battery after a preset on period to save battery life ( Reference 1 ). This Design Idea presents a simpler way to perform the same function (Figure 1). Two gates of IC 1 , a ...
A random-bit-sequence generator is basic equipment for prototyping and testing any data-transmission system. You use such a generator when measuring BER (bit-error rate) and pattern-dependent effects in a transmission system. Such effects can ...
