Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A signal driver comprising: a pair of signal lines; a receiver circuit; and a driver circuit connected to said hair of signal lines, said driver circuit including two pairs of totem pole connected transistors, each said pair of totem pole connected transistors being connected between a circuit ground voltage and a voltage less than the supply voltage to said receiver circuit, the transistor connected to said voltage less than said supply voltage from each pair in operation, receiving a common signal in connection with controlling the precharge of said pair of signal lines to a selected voltage; said receiver circuit connected to said pair of signal lines and in operation outputting logic high and logic low voltage levels from said precharged signal lines.
Claim 2
Dependent Claim
123 words
A signal driver comprising: a pair of signal lines; a receiver circuit; and a driver circuit connected to said hair of signal lines, said driver circuit including two pairs of totem pole connected transistors, each said pair of totem pole connected transistors being connected between a circuit ground voltage and a voltage less than the supply voltage to said receiver circuit, the transistor connected to said voltage less than said supply voltage from each pair in operation, receiving a common signal in connection with controlling the precharge of said pair of signal lines to a selected voltage; said receiver circuit connected to said pair of signal lines and in operation outputting logic high and logic low voltage levels from said precharged signal lines.
Claim 3
Dependent Claim
41 words
A signal driver as recited in claim 1 wherein said driver circuit further includes a third pair of transistors, each transistor from said third pair being connected to an associated one of said signal lines from said pair of signal lines.
Claim 4
Dependent Claim
62 words
A signal driver as recited in claim 1 wherein said receiver circuit comprises: first and second transistors each connected to a common precharge control line; a third transistor connected to a drain/source of the first transistor and an output of said receiver circuit; and a fourth transistor connected to a drain/source of the second transistor and an output of said receiver circuit.
Claim 5
Dependent Claim
37 words
A signal driver as recited in claim 3 wherein said receiver circuit further comprises: a fifth transistor connected to the gate of said third transistor; and a sixth transistor connected to the gate of said fourth transistor.
Claim 6
Dependent Claim
31 words
A signal driver as recited in claim 1 wherein the voltage less than the supply voltage to said receiver circuit is one half of the supply voltage to the receiver circuit.
