Patent ID: 7746921

Claim:
A low-power digital data driver circuit, comprising: a. a first resonant circuit that generates a first output that oscillates between a first highest potential voltage and a second intermediate potential voltage, and b. a second resonant circuit that generates a second output that oscillates between said second intermediate potential voltage and a third lowest potential voltage, and c. a forcing circuit that drives said first and second resonant circuits at the same frequency which is substantially the same as their common resonant frequency and drives said first resonant circuit 180-degrees out of phase with respect to said second resonant circuit, and d. a differential signal pair consisting of a true data line and a complement data line, and e. a data switch with two settings including a first setting that connects said first output of said first resonant circuit to said true data line of said differential signal pair and connects said second output of said second resonant circuit to said complement data line and a second setting that connects said first output of said first resonant circuit to said complement data line of said differential signal pair and connects said second output of said second resonant circuit to said true data line, and whereby said true data line of said differential signal pair can be driven to said first highest potential voltage as an integral part of said first resonant circuit while said complement data line is driven simultaneously to said third lowest potential voltage as an integral part of said second resonant circuit or vice versa depending on the setting of said data switch, which enables said true data line to be driven either to said first highest potential voltage or to said third lowest potential voltage on sequential cycles of the resonant circuit outputs in response to the settings of said data switch while said complement data line is driven simultaneously to the opposite state with low power dissipation associated with resonant circuits.
