James Mahoney EDN The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in ...

Ajoy Raman EDN This Design Idea presents a minimal-parts-count, wide-range voltage doubler using the inherent voltage-doubling characteristics of a one-transformer push-pull dc/dc converter. The implementation uses a high-voltage Darlington-array ...

Wayne Ryder Electronic Design The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 MHz than buying a ...

Marián Štofka EDN Pulse generators often need voltage comparators with accurately defined hysteresis, and such comparators need bipolar voltage references. Most voltage-reference-cell ICs are referenced to their low-side supply rail. ...

Goh Ban Hok EDN An SOC (system on chip) normally requires two power supplies one for the core supply and the other for the I/O. To properly power up the chip, you need to get one of the power supplies ready before the other, according to the ...

Samuel Kerem Electronic Design The filter described below is useful for detecting a signal that’s closely surrounded by spurs, even when the task is complicated by the frequency of the signal of interest wandering by a few percent. For ...

Aurel Gontean EDN Linear regulators are easy to implement and have better noise and drift characteristics than switching approaches. Their largest disadvantage is inefficiency: excess energy dissipated as heat. Several well-known techniques are ...
