Abstract
Three schemes for linearising the transconductance of the basic differential pair in subthreshold CMOS are examined: (i) multiple asymmetric differential pairs, (ii) source degeneration via symmetric diffusers, and (iii) source degeneration via a single diffuser. Using a maximally flat optimising criterion, the linear range of the basic differential pair can be increased by 4-8 times
