Patent ID: 7436215

Claim:
A transmitter comprising: a first circuit coupled to an input port of the transmitter, the first circuit including an input port and an output port and an inverter including no more than two transistors including a first transistor and a second transistor, the first transistor having a source/drain directly connected to a source drain of the second transistor and a first gate of the first transistor and a second gate of the second transistor both coupled directly to the input port of the transmitter, wherein the first transistor and the second transistor of the inverter include a n-type metal-oxide semiconductor field-effect transistor connected in series with an p-type metal-oxide semiconductor field-effect transistor and wherein the n-type metal-oxide semiconductor field-effect transistor is between about two and about three times larger than the p-type metal-oxide semiconductor field-effect transistor; and a second circuit including a second circuit input port coupled to the output port of the first circuit, the second circuit including a second circuit output port coupled to an output port of the transmitter, wherein the first circuit is sized with respect to the second circuit such that for a pulse signal applied to the input port of the transmitter, the transmitter generates an output signal having a rise-time and a fall-time that are substantially equal at the output port of the transmitter, wherein the transmitter is operable to transmit at a signal level, and the first circuit and the second circuit are coupled to a supply potential having a value of about twice the signal level.
