Abstract: Various circuit techniques for implementing ultra high speed circuits use current-controlled CMOS (C3MOS) logic fabricated in conventional CMOS process technology. An entire family of logic elements including inverter/buffers, level shifters, NAND, NOR, XOR gates, latches, flip-flops and the like are implemented using C3MOS techniques. Optimum balance between power consumption and speed for each circuit application is achieve by combining high speed C3MOS logic with low power conventional CMOS logic. The combined C3MOS/CMOS logic allows greater integration of circuits such as high speed transceivers used in fiber optic communication systems.

Abstract: Systems, methods and apparatus for transferring data at a high rate. Examples may provide transmitters and receivers that transfer data at a high rate by encoding the data to be transmitted such that the circuits of the transmitter and receiver operate in their high-gain states. The encoded signal may have an average value that is independent of the data that is conveyed by the transmitted signal. In other examples, the encoding may shape the data signal into a data signal having a high-pass characteristic. When the high-pass encoded signal is transmitted through a channel having a low-pass transfer function, the resulting output signal may have much lower ISI compared to a un-encoded input signal. Transmit and receive circuits, such as amplifiers, laser, and photo-diodes, are biased to operate in their high-gain regions when receiving the encoded data in order to provide high-bandwidth and shorter transition times.

Abstract: A high speed data communication system uses a single-ended bus architecture with a reference signal extracted from a differential periodic signal that is transmitted along with single-ended data. By using a periodic signal such a clock signal with approximately 50% duty cycle, a much more stable and accurate reference signal is established for receiving single-ended data.

Abstract: The present invention relates in general to integrated circuits, and in particular to method and circuitry for implementing an improved phase-locked loop (PLL) in complementary metal-oxide-semiconductor (CMOS)technology using current-controlled CMOS (C3MOS) logic. In an exemplary embodiment, a phase-locked loop includes a phase-frequency detector, a Gm cell block, a low pass filter and a voltage controlled oscillator. These various elements of the phase-locked loop are connected to one another in a fully differential manner, i.e., each element has an input and/or an output each having at least a differential signal. In one embodiment, each of these various elements of the phase-locked loop is implemented using C3MOS logic.
