For the data drivers of TFT-LCDs with high gray-scale above 8-bit, OP-Amps with high voltage accuracy less than 1 mV, is needed. Accordingly, the offsets voltages of the OP-Amps should be compensated ...

A new circuit technique for voltage gain enhancement in CMOS op amp design suitable for low voltage and high speed operation is presented in this paper. A negative conductance is used to cancel the ...
