The second pre-driver circuit pre-drives a second data input signal to generate a second pre-driving output signal, wherein the first data input signal and the second data input signal are a differential input of the output driver. The second driver circuit drives the second pre-driving output signal to generate a second data output signal.

Abstract: Systems and methods for detecting the presence and/or location of defects (e.g., incomplete solders, broken cables, misconnections, defective sockets, opens, shorts, etc.) along electrical lines are described. The systems and methods described herein may use time-domain reflectometry (TDR), a measurement technique used to determine the characteristics of electrical lines by observing reflected waveforms. TDR may be performed in some embodiments by determining the times when a first event and a second event occur, and by determining the space traveled by a probe signal based on these times. The first event may occur when a first signal transition crosses a first threshold and the second event may occur when a second signal transition crosses a second threshold, where the second signal transition may arise in response to the first signal transition reflecting against a defect along the electrical line.

Abstract: Systems and method for supply noise suppression in electronic circuits are described. The systems described herein may prevent or at least limit noise coupling from a supply line to a load, and may further prevent or at least limit noise generated at the load from coupling to the supply line. The systems and methods described herein may be particularly useful in systems-on-chip with multi-level interposers, in which multiple supply lines are used to provide different voltage levels to the chip. In these systems, in fact, the supply lines can exhibit large impedances, which may in turn promote noise coupling from one circuit to another. In one example, a voltage regulator is provided that includes a linear regulator and an active shunt circuit.

Abstract: In an RF transceiver front-end device that operates in a receiving mode, a first transformer circuit generates, based on an external RF signal received by an antenna, a first induction signal that passes through a switch unit, and that is amplified by a low noise amplifier circuit and then demodulated by a demodulation circuit to thereby generate a reception signal. When the RF transceiver front-end device is in a transmitting mode, a power amplifier circuit generates, based on a modulated signal generated by a modulation circuit through modulation of an external transmission signal, an amplified output. A second transformer circuit then generates, based on the amplified output, a second induction signal that is thus radiated by the antenna.
