Abstract:
The present disclosure includes switched capacitor transmitter circuits and methods. In one embodiment, a digital data signal is thermometer encoded and a negative thermo-encoded signal is bit order reversed to control capacitors in a switched capacitor transmitter circuit. In another embodiment, the present disclosure includes a plurality of switched capacitor transmitter circuits coupled to inputs of an inductive network. The inductive network combines voltages from the switched capacitor transmitter circuits to produce a combined voltage on an output.
