The ultrasound diagnosis apparatus according to a disclosed embodiment may include a display unit, a user interface, a memory for storing one or more instructions, and a processor for executing the one or more instructions to acquire ultrasonic data using a probe that moves on the basis of a scanning line, control the display unit to display the body shape of a user, control the user interface to acquire information on the scanning line, and acquire, on the basis of the body shape and the information on the scanning line, an ultrasonic image volume from the ultrasonic data.

Abstract: A phase detector apparatus and method used for clock recovery from a data signal is provided. The phase detector provides phase correction signals to a clock signal generator, where the phase correction signals are only generated if a predetermined data sample pattern is observed. In particular, the predetermined data sample pattern is preferably a transition from one to zero. Thus, transitions from zero to one will not provide a valid phase update output signal, even though a transition has occurred. In other embodiments the predetermined data sample pattern is preferably a one to zero transition preceded by an additional logic one sample.

Abstract: A noise tolerant voltage controlled oscillator is described. The voltage controlled oscillator include a varactor element as part of an LC tank circuit. The varactor element is biased by a bias signal and a bias-dependent control signal. The bias-dependent control signal tunes the LC tank circuit. Because the control signal is bias-dependent, noise and other deleterious influences do not cause the varactor element to deviate in capacitance. Instead, the bias-dependent control signal is a tuning signal that is centered around the bias signal, which allows the varactor element to provide a constant capacitance in the event of a varying bias signal.
