- LINE POWERED 60Hz CLOCK GENERATOR
This circuit is connected to the 120vac power line and transfers 60Hz clock pulses to a logic circuit. The optoisolator used provides 5000 volts
of isolation between the power line and the logic side of the circuit.

- WIDE BAND ZERO CROSS DETECTOR
This circuit was designed to convert a low amplitude 40KHz signal into a clean square wave signal. It will work with inputs as small as
5mv peak-to-peak or as large as 3 volts peak to peak. The input frequency can range from a few kilohertz to about 150KHz.

| Current Feedback Amps Square up Fast Signals: 06/23/94 EDN-Design Ideas /
(Electronic Circuit diagram added 03/03) Using current-feedback amplifiers to convert signals from sine waves to square waves for DSP confers
advantages over the more common comparator approaches. Current-feedback amplifiers have wide bandwidths and relatively small and constant
propagation delays. These small, constant delays help meet the setup-and-hold requirements of digital logic. Typically, current-feedback
amplifiers have delays from 1.1 to 5 nsec.... |

tag impulses with zero crossing circuit: 01/24/2002 EDN - Design Ideas / (added 11/03) A "constant-fraction
discriminator" usually performs the time-tagging of impulsive events, which have a peaking time of the signal amplitude. The implementation of
this technique requires a delay in the input signal of approximately the same amount as the signal's rise time. You can attain this delay by
using a coaxial cable of an appropriate length. |
