Abstract: A receiver for receiving a data signal, comprising, an analog-to-digital converter configured to convert the data signal into digital data, a first-in-first-out buffer configured to determine a frame boundary of the digital data by referring to a comma index to output the digital data in units of data frames according to the determined frame boundary, a decision feedback equalizer configured to process a data frame output from the first-in-first-out buffer through a decision feedback equalization operation, wherein feedback data used in the decision feedback equalization operation of the data frame uses a predetermined fixed pattern, and a comma detector configured to generate the comma index by comparing a determined value of the data frame with the predetermined fixed pattern. The data frame may include a preceding data field in which a message is stored and a subsequent comma field having the same bit value as the fixed pattern.

Abstract: A power supply and a gate driver includes a power switching element to control current, a control circuit to output a control signal for opening or closing of the power switching element, and a gate drive circuit to open or close the power switching element in accordance with the control signal. The gate drive circuit includes a first inductive circuit connected to a supply voltage source, and a second inductive circuit connected to an input stage of the power switching element, and transfers electrical energy stored in the input stage of the power switching element, using the first and second inductive circuits. Accordingly, electrical energy supplied to the input stage of the power switching element during an ON state of the power switching element is again recovered during an OFF state of the power switching element.

Abstract: The present disclosure relates to successive approximation register analog-to-digital converters. An example successive approximation register analog-to-digital converter includes a first sampling and holding circuit that samples an analog signal at a first point in time and generates a first input voltage, a second sampling and holding circuit that samples the analog signal at a second point in time and generates a second input voltage, and a first analog-to-digital converter. The first analog-to-digital converter performs a feed forward equalization function by receiving the first input voltage and the second input voltage, sampling the first input voltage and the second input voltage, and outputting a multi-bit digital signal based on a sampling result of the first input voltage and a sampling result of the second input voltage.
