“…In order to meet the today market requirements for lowvoltage/low-power portable electronics and communication systems a significant research effort has been done for developing low-voltage log-domain circuits [1][2][3][4][5][6][7][8][9][10][11]. The already introduced log-domain differentiator topologies [12][13][14][15][16][17] are not compatible with the aforementioned requirement due to the fact that the minimum supply voltage requirement is equal to 2V BE ?…”

A new family of low-voltage log-domain differentiator topologies is introduced in this manuscript. Their attractive characteristic, in comparison to the already published structures, is that the minimum supply voltage requirement is equal to a base-emitter voltage plus twice the saturation voltage of MOS transistors operated in strong inversion, giving potential for employment in modern low-voltage environments. The realization of the corresponding transfer function is achieved by introducing a set of complementary operators which allow the realization of low-voltage active building blocks in the logdomain. Both linear and non-linear performances of the introduced configurations have been studied through simulation results.
