An apparatus may include a first clock generator configured to receive an input clock signal, and generate two or more first-level clock signals of a track-and-hold circuit, a phase interpolator configured to generate an interpolated clock signals, wherein the interpolated clock signal is based on the two or more first-level clock signals, and a second clock generator configured to generate two or more second-level clock signals based on the interpolated clock signal, wherein the phase of the two or more second-level clock signals relative to the phase of a respective first-level clock signal is determined, at least in part, by the phase of the interpolated clock signal.

Adaptive alignment of sample clocks within analog-to-digital converters

Various aspects of amplifying amplitude of a pulse are disclosed herein. In sonic embodiments, a device includes driver circuitry that receives an input pulse swinging or transitioning between a first reference voltage and a second reference voltage higher than the first reference voltage, In some embodiments, the driver circuitry generates a driving pulse swinging between a third reference voltage and the second reference voltage according to the input pulse, where the third reference voltage is between the first reference voltage and the second reference voltage. In some embodiments, the device further includes a transistor coupled to the driver circuitry. In some embodiments, the transistor outputs an output pulse swinging between the first reference voltage and an output voltage according to the driving pulse from the driver circuitry, where the output voltage is higher than the second reference voltage.

Pulse amplifier

Methods, systems, and apparatuses are described for reducing the latency in a transceiver. A transceiver includes a high latency communication channel and a low latency communication channel that is configured to be a bypass channel for the high latency communication channel. The low latency communication channel may be utilized when implementing the transceiver is used in low latency applications. By bypassing the high latency communication channel, the high latency that is introduced therein (due to the many stages of de-serialization used to reduce the data rate for digital processing) can be avoided. An increase in data rate is realized when the low latency communication channel is used to pass data. A delay-locked loop (DLL) may be used to phase align the transmitter clock of the transceiver with the receiver clock of the transceiver to compensate for a limited tolerance of phase offset between these clocks.
