I am having a chain of differential amplifier stages and at the end a comparator to compare the signal with some threshold value.
For single Ended amplifiers I give amplifier chain output at one input of Comparator and Threshold Voltage at other Input of comparator to get result.
But how do I do it when I have differential Output of Amplifier Chain?
Is it ok to give Vin_P + Vth/2 at one input of comparator and Vin_N + Vth/2 at other end of comparator?
where Vin_P and Vin_N are differential output of Amplifier stages that are to be fed into discriminator
In schematic, circuit in red is Analog chain whose output is intended to be compared with some reference value by discriminator (As seen in blue)
