Claim:
1. A driver for performing efficient low-power high-swing modulation, comprising: a) a first plurality of N controllable switching elements having a common contact and a free contact and introducing low impedance between said contacts in response to a low control level and vice versa; b) a second plurality of N controllable switching elements having a common contact and a free contact and introducing high impedance between said contacts in response to a low control level and vice versa; c) a DC power supply (V d) a plurality of N voltage dividers, each of which consisting of two serially connected resistors connecting between a free contact of a controllable switching element from said first plurality and a free contact of a controllable switching element from said second plurality, where each two controllable switching elements connected by a voltage divider forming a pair; e) a plurality of N control inputs, each of which jointly controlling the control inputs of a different pair; and f) a common output connecting between all N common points of all pairs of serially connected resistors forming said N voltage dividers.
