The present disclosure provides apparatuses for converting a current signal into a voltage signal. In some embodiments, a current-to-voltage converter includes a transimpedance amplifier, a first filter circuit coupled between an input node of the transimpedance amplifier and an internal node of the transimpedance amplifier, and a second filter circuit coupled between the input node of the transimpedance amplifier and an output node of the transimpedance amplifier. The first filter circuit is configured to operate as a low-pass filter with respect to the current signal. The second filter circuit is configured to operate as a band-pass filter with respect to the current signal. In some embodiments, a transceiver includes a receiver circuit that includes a current-to-voltage converter, a transmitter circuit. The current-to-voltage converter is configured to convert a current signal corresponding to a first reception signal into a voltage signal corresponding to a second reception signal.

Current-to-voltage converter, transceiver, and wireless communication device

A transmitter includes a multiplexer, control logic and a voltage mode driver. The multiplexer generates a plurality of time-interleaved data signals based on a plurality of input data signals and multi-phase clock signals. The plurality of input data signals are input in parallel. Each of the plurality of input data signals is a binary signal and has two voltage levels that are different from each other. The control logic generates at least one pull-down control signal and a plurality of pull-up control signals based on the plurality of time-interleaved data signals. Each of the plurality of pull-up control signals has a voltage level that is temporarily boosted. The voltage mode driver generates an output data signal based on the at least one pull-down control signal and the plurality of pull-up control signals. The output data signal is a duobinary signal and has three voltage levels that are different from each other.

Transmitter and receiver for low power input/output and memory system including the same

The present invention relates to a method and device for providing an advertisement, in which a service device extracts a list of customers to be targeted based on authentication based information, and a user terminal device corresponding to the extracted list of customers collects non-authentication based information to provide an advertisement to an advertisement target application operated by a third party, and a recording medium in which a computer program for performing the method is recorded.

Method and device for providing advertisement

A method of providing a one-barcode service, and more particularly, to a method of providing a one-barcode service, in which a plurality of pieces of card information are registered using a single barcode, alliance company information in connection with each piece of card information are managed using the single barcode, and an alliance company service is used, and a system therefor. The method of providing the one-barcode service includes executing, by a terminal, a one-barcode service application and querying a service providing server for one-barcode issue information, receiving, by the terminal, one-barcode issue information including one or more of pieces of pre-issued card information corresponding to one-barcode identification information from the service providing server, and performing, by the terminal, a registration of alliance company information capable of being registered corresponding to the card information included in the one-barcode issue information by being in connection with the service providing server.

Method for providing for one-barcode service, and system therefor

An air conditioner management system and a method for controlling an air conditioner are disclosed. A user interface device provides a user interface to sense a user measure indicating a user opinion regarding operation of an air conditioner, generates feedback data associated with the sensed user measure, and transmits the generated feedback data. A central management device receives and stores the feedback data transmitted by the user interface device and calculates a set value to control the air conditioner based on the received feedback data and previously stored feedback data.
