摘要： Provided are a pipeline Analog-to-Digital Converter (ADC) without a front-end Sample-and-Hold Amplifier (SHA) and a method of controlling the same. The method includes the steps of: simultaneously sampling, at an ADC and a residual signal generator included in a first stage, an analog input signal and respectively generating a first sampling value and a second sampling value; holding, at the residual signal generator, the second sampling value, and simultaneously amplifying and converting, at the ADC, the first sampling value into a corresponding digital code; and generating, at the residual signal generator, a residual signal using the digital code. The pipeline ADC and method of controlling the same minimize sampling mismatch caused by removing a front-end SHA, thereby ensuring stable performance without a front-end SHA. Since a front-end SHA is not used, it is possible to reduce chip size and power consumption, and improve the performance of the ADC.

摘要： Provided is an algorithm analog-to-digital converter (ADC). The algorithm ADC obtains two digital outputs through different capacitor connections for one analog input signal and adds the digital output signals to obtain a final output value, so that a mismatch factor of the capacitor is removed to minimize a linearity limitation resulting from the capacitor mismatch. In addition, the algorithm ADC minimizes power consumption by making the operating frequency slow at a cycle requiring a high resolution and making the operating frequency fast at a cycle requiring a low resolution, i.e., outputting different operating clock frequencies according to a required resolution.

摘要： The present invention relates to an earring-type microphone to be hung on and used in the ear, and comprising: fixing members fixed to both ears of a user; a cable manufactured from an elastic member, of which both ends are respectively positioned at two fixing members, such that one side of the cable comes into close contact with the neck of the user; speakers respectively coupled to both ends of the cable; and a microphone part provided at one side of the cable and inputting a voice, wherein if force is applied to the microphone part when the user inputs the voice through the microphone part, the cable is stretched such that the microphone part moves from the neck of the user toward the area around the mouth, and if the force applied to the microphone part is removed, the microphone part comes into close contact with the area around the mouth of the user by the elastic force of the cable. The present invention is fixed to a part of the user's body during normal activities so as to increase the activeness of the user. That is, the present invention is formed in a manner, in which both ends of the fixing member latch onto the ear, so as to eliminate, compared to a conventional microphone, the concern over the microphone being removed from the ear, even though the user performs various actions while wearing the microphone, and can be fixed to the ears only by an operation of simply widening and releasing the fixing members, such that the wearing and the removal of the microphone is easy.

摘要： The present invention relates to an ear device for fixing an earphone, comprising: a fixing body which is formed in the shape of a C-shaped ring so as to be worn on and fixed to an auricle while surrounding the rear part of the auricle; an earphone module, positioned in a groove in the front part of the auricle, for transferring sound to an ear hole; and a support connector which extends in the shape of a ring that traverses a user's auricle from one portion of the fixing body to the earphone module, the support connector being formed of an elastic body or flexible metal so as to, according to deformation of the support connector, enable the fixing body and the earphone module to be separated from each other or to approach each other so that the fixing body and the earphone module are engaged with and fixed to each other on the auricle. The fixing body has a first coupling member on one side thereof, the earphone module has a second coupling member on one side thereof, and both ends of the support connector are detachably configured so as to be separated from and coupled to the first coupling member and the second coupling member so that it is possible to use the fixing body and the earphone module by integrally coupling the fixing body and the earphone module, or it is possible to use the earphone module alone according to a user's need. The earphone module further comprises a sound box, a length adjustment unit and an accessory, and the accessory and the fixing body have an electronic chip such as an RFID or authentication key embedded therein. Thus, the present invention has effects of: firmly and stably fixing an earphone to a user's ear with the least number of constitutional elements; pre-empting occurrence of ear pain and hearing impairment since the earphone is not directly inserted into the user's ear hole; and enabling the user to hear ambient sound, thereby enabling the user to rapidly cope with surrounding circumstances and escape from safety accident-related danger.
