  2. At the end of the DI for a Simple log-scale audio meter (Ref. 1), I promised to show how to upgrade it to work better. With these fixes, it now has near-digital performance, with faster response and smoother operation. Even this supersized version ...

  2. I recently purchased a new oscilloscope for home use. It’s a 250 MHz scope, but I was curious what the actual 3 dB frequency was as most scopes have a bit more upper end margin than their published rating. The signal generators I have either ...

  3. When a design needs auxiliary voltage rails and the associated current loads are modest, capacitor pump voltage multipliers are often the simplest, cheapest, and most efficient way to make them. The simplest of these is the diode pump voltage ...

  4. When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources that are commonly provided by capacitive ...
