Hi everyone,
I am working on VCO based delta sigma ADC. I want to know how to convert two outputs of VCO based quantizer into just one for feedback DAC.
I will tell you the basic structure is that i am using a 9 stages VCO and then connect two DFFs one after the other and then connect the output of these two DFFs to one XOR which gives one output. And similar procedure is performed in negative end which mean that circuit is differential. Now finally we get two different output of two different XOR (positive and negative end). I want to combine these two outputs and make just one to give feedback to DAC.
kindly need Help .
