Fig. 10.19 An exemplary CMOS implementation of the MIDCC based upon the one proposed by
Horng et al. [ 58 ]

A typical CMOS implementation of MIDCC employing N number of differen-
tial pairs, current mirrors and current repeater is shown in Fig. 10.19 and appears to
be self-explanatory. When implemented in TSMC 0.35 ʼ m technology, it exhibited
