Abstract: A system and a method for detecting a low-frequency periodic signal (LFPS) include at least one comparator performing a threshold comparison on an analog input signal over a period of time. A sampling circuit generates digital signals by sampling an output of the at least one comparator. A digital detection circuit applies a set of detection rules to the digital signals. The detection rules are configured to detect a presence or an absence of an LFPS based on predefined criteria concerning characteristics of the digital signals.

Abstract: Disclosed is a high-swing voltage-mode transmitter or line driver. The transmitter can operate over a wide range of supply voltages. Increasing the available output swing merely involves increasing the supply voltage; the circuit adapts to maintain the desired output impedance. This allows for a tradeoff between output amplitude and power consumption. Another advantage of the proposed architecture is that it compensates for process, voltage, and temperature (PVT) and mismatch variations so as to keep rise and fall times matched. This feature reduces common-mode noise and hence EMI in systems in which the transmitter is used.

Abstract: An electro-optic switching device, namely an optical phased array (OPA) or a reprogrammable optical phased array (ROPA), that can accommodate high switching speeds, reduced losses and increased efficiency while being adapted to operate at various wavelengths using suitably low activation voltages is presented. The ROPA designs presented herein are generally comprised of an electro-optic (EO) crystal electrically mounted to a high-voltage CMOS chip activated to apply an array of activation voltages across the crystal and induce a refractive index profile therein, such profile adaptable to selectively control and manipulate an optical beam interacting with the device.
