Dear Sir,
I'm working under reimann pump in cmos technology and i found your paper is very interesting.
I'm designin a 3 bit binary differential current steering DAC using transmission gate as a switch in the top and the bottom of my circuit. Thus my problem that when the binary switch from '001' to '110', the rised slope and decreased slope are not identical, as can be seen in figure below
It is necessary that the descent slope and the rise slope should be equal. This provide an asymmetry of the curve and i can’t reconstrut my input signal which is a sinusoidal signal. Moreover, each transition where all the bits change, the rised slope and the decreased slope i are not equal.
So, how can I adjust this asymmetry and maintain the same slope in the rise and decrease direction when all the 3 binary bits are changed from the the first transition to the second.
I’m so grateful if you can help me ;
Best Regards
