hallo,
In the attachment(taken IEEE article) there are 12 reference voltages are paired with input signal. The article said,
1.eight differential pairs are needed for a folding a signal
2.two additional differential amplifiers(with ref9 and ref10) are used for the extension of the folding signals for the low and high side of the input range to allow interpolation in that region.
3.another differential amplifier(with ref11) is needed for proper DC balance
4.Last differential pair is dummy structure for capacitance compensation
Can someone explain me the 2.sentence? It is unclear.
total intersection between Vout+(y1) and Vout-(y2) against Vin will be 8 or 12?
Thx very much
