摘要: A tunable bandpass filter to provide a filtered differential clock signal in response to an input differential clock signal, where an embodiment comprises a transistor pair loaded by tunable loads, and a feedback circuit to tune the tunable loads. In some embodiments, the feedback circuit tunes the loads to maximize a small-signal differential gain. In other embodiments, the feedback circuit tunes the loads to minimize a metric indicative of jitter in the filtered differential clock signal. Other embodiments are described and claimed.

摘要: An all-digital delay measurement circuit (DMC) constructed on an integrated circuit (IC) die characterizes clocking circuits such as full phase rotation interpolators, also constructed on the IC die. The on-die all-digital DMC produces a digital output value proportional to the relative delay between two clocks, normalized to the clock period of the two clocks.

摘要: For one disclosed embodiment, an integrated circuit may comprise an internal transmission line in one or more layers of the integrated circuit. The internal transmission line may be coupled to receive a signal from an external transmission line at a first end of the internal transmission line without use of termination circuitry. The internal transmission line may transmit the signal passively to a second end of the internal transmission line. The integrated circuit may also comprise first circuitry having an input coupled to the internal transmission line at a first location of the internal transmission line to receive the signal and second circuitry having an input coupled to the internal transmission line at a second location of the internal transmission line to receive the signal. The second location may be different from the first location. Other embodiments are also disclosed.
