The paper presents a simple low-voltage transresistor attractive for on-chip analog-signal-processing. The proposed circuit offers not only an almost rail-to-rail operation and quite good linearity of DC transfer characteristic but also reasonably low value of its output resistance. This enables a voltage mode operation even if the transresistor is loaded by a not necessarily very high loading resistance. The obtained result is due to adding to the transresistor-input-stage a simple rail-to-rail voltage follower. The presented solution is an original proposal of the author. Input stage of the transresistor is built of only 4 MOS transistors and creates a simple quasi-linear current-to-voltage convertor. Output stage of it is built of 9 MOS transistors, plays a role of a very precise atypical voltage follower. In respect of simplicity and headroom, the proposed follower is better than conventional OA-based voltage followers. Preliminary simulation results are in a good agreement with the theory presented.
