Abstract:
A time-to-digital converting circuit and a pressure sensing device using the same are provided. The circuit includes: a delay time-varying unit generating a reference signal having a fixed delay time, and a sensing signal having a variable delay time in response to an impedance of an externally applied signal; and a delay time calculation and data generation unit calculating a delay time difference between the reference signal and the sensing signal, and generating digital data having a value corresponding to the calculated delay time difference. Accordingly, the digital data are generated using the delay time varied in response to the externally applied signal, so that the size of the time-to-digital circuit is significantly reduced. In addition, an affect due to external noises is minimized.

Abstract:
An apparatus and method for transmitting data in a wireless communication system using Code Division Multiplexing (CDM) are provided. A code controller distinguishes a Walsh code used for spreading during data transmission and a Walsh code unused for spreading based on a signal-to-interference ratio required by the system, and separately provides the Walsh codes. A CDM multiplexer CDM-multiplexes input data using the Walsh code used for spreading, provided from the code controller. A code modulator modulates input data using the Walsh code unused for spreading, provided from the code controller. A multiplexer multiplexes outputs of the CDM multiplexer and the code modulator.
Abstract:
A touch panel device and a method for detecting a contact position are provided. The touch panel device includes a touch panel including a first touch pattern, the first touch pattern having a plurality of first touch pads connected in series; and a touch sensor for applying a clock signal to one terminal of the first touch pattern, receiving a first delayed clock signal from the other terminal of the first touch pattern, and generating contact position data corresponding to a contact position of an object using a difference in delay time between the clock signal and the first delayed clock signal. Thus, since the plurality of touch pads are connected in series, the contact position of the entire touch panel can be sensed with only one touch sensor, and the touch pad has a greater area than the connection line for a distinguished difference in resistance between the touch pad and the connection line, such that the contact position can be accurately detected.
