Recently I released a design for what I hope is a Precision Diode Wideband AC-DC converter. It got me to thinking If I coupled this to a linear sweep generator and a wide rang VCO 100Hz-200 KHz With an oscope I might have the basis for a network analyzer. The key is the VCO. My first thought is to make Schmitt trigger with variable set points similar to how a 555 does it and make a hysteric Oscillator ( I'll draw and post the concept later but it occurs to me that someone has a better idea, So here I am hat in hand asking for ideas, and no, I have not Googled it yet.
