METHODS AND DEVICES FOR AN ENERGY EFFICIENT DIGITAL TO ANALOG CONVERSION

Methods and devices for an energy efficient digital to analog conversion are disclosed. With the achievable sampling rates and output voltage levels, high power RF signals can be synthesized. A plurality of pulses are generated and coupled onto transmission lines. On the other end of the transmission line the pulses are either reflected or transmitted to a load line depending on the status of a termination element. In one embodiment the reflected pulses are collected and sent to a load. The energy in the transmitted pulses can be recovered and reused. In another embodiment the transmitted pulses are collected and transmitted to a load and the energy in the reflected pulses is recovered and reused.
