Introduction

Goal coder decoder

Coder design voltage controlled oscillator

Coder design large voltage drop

Coder design low voltage drop

Coder design common collector amp. this would work too

Coder design common collector amp.

Coder design galvanic isolation

Coder Design VCO control voltage

Coder Design VCO DAC

Decoder design VCO DAC PLL

Decoder design VCO DAC PLL ADC

Decoder design VCO DAC PLL ADC higher frequency oscillations expect some noise

Decoder design VCO DAC PLL ADC higher frequency oscillations BP filter expect some noise

Design VCO DAC PLL ADC BP filter only one one-sided supply voltage regulator voltage regulator

It works VCO DAC PLL ADC BP filter voltage regulator voltage regulator

It works, under one condition VCO DAC PLL ADC BP filter voltage regulator voltage regulator

Houston, we have a problem VCO DAC PLL ADC BP filter voltage regulator voltage regulator SNR too low

How to increase SNR? VCO DAC PLL ADC BP filter voltage regulator voltage regulator lower noise power lower BW

How to increase SNR? increase signal power VCO DAC PLL ADC BP filter voltage regulator voltage regulator common collector amp.

Solution? VCO DAC PLL ADC BP filter voltage regulator common collector amp.
