Sine to Square Wave Converters Circuits

Current Feedback Amps Square up Fast Signals: 06/23/94 EDN-Design Ideas

Current Feedback Op Amps Save Power In Photodiode Apps : 09/30/02 Electronic Design - Ideas for Design / Current-feedback amplifiers offer high bandwidth with minimal power-supply current draw. However, they're rarely used as transimpedance amplifiers in photodiode applications due to the high current noise of their inverting inputs.

Self Powered Sine to Square Wave Converter: Converts sine to square waves without a power-source Useful as a test instrument for audio purposes

Time tag impulses with zero crossing circuit: 01/24/2002  EDN - Design Ideas / 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. .

Unique discrete zero-crossing detector: 04/05/99 Electronic Design - Ideas for Design /  A zero-crossing detector delivers an output pulse that synchronizes other circuitry to the transitions through zero volts of a sinusodial source for both polarity excursions.
