Abstract: A tunable current mode integrator for low-frequency continuous-time filters that requires a reduced amount of area when implemented in an integrated circuit (IC). The integrator includes input and output transistors, and cross-coupled current mirrors, integration capacitors, and operational transconductance amplifiers (OTAs) that form a feedback structure with the input transistors. Input currents are converted to small current swings within the OTAs, and are subsequently integrated by the capacitors. Resulting integrated voltages are converted to output currents by the output transistors.

Abstract: A synchronous interconnect structure is provided for transmitting and receiving source synchronous signals. The receiver of the synchronous interconnect structure continuously monitors the phase relationship between the source clock signal and each transmitted data signal. In this manner, the synchronous interconnect structure can perform signal timing alignment for each transmitted clock and data signal in near real time fashion without impacting data transmission rates across the synchronous interconnect structure.

Abstract: An electronic apparatus for receiving source synchronous signals is provided. The receiver continuously monitors the phase relationship between each data signal and the source synchronous clock signal. In this manner, the electronic apparatus can compensate for phase discrepancies that occur over time without having to interrupt any data operations.
