A BC-mode image with an improved frame rate in an ultrasound system is formed. A transmit/receive unit forms first and second receive signals responsive to first and second control signals. An image processing unit is configured to form a B-mode image and a C-mode image based the first and second receive signals and to combine them to form a BC-mode image. The control signal generates a third control signal for a B-mode scan along scan lines, which are not within the color box to form third receive signals. The control unit repeatedly generates the second and third control signals. The image processing unit is further operable to form a B-mode image based on the third receive signals and the second signals.

A matching circuit for two-channel Analog to Digital Converters (ADCs) is disclosed in which two ADCs convert analog signals of two channels to digital signals with the same operational characteristics. A bias voltage supplier operates in such a way that analog signals of first and second channels are each converted to digital signals by first and second ADCs, a bias voltage supplier generates a DC bias voltage to set up DC levels of the analog signals of the first and second channels, and a reference voltage supplier generates a reference voltage and supplies it to the first and second ADCs. Therefore, the first and second ADCs convert the analog signals to digital signals with the same operational characteristics.

A reference voltage supplying circuit is disclosed, wherein the circuit generates stable maximum reference voltage and minimum reference voltage to a pipeline Analog to Digital Converter (ADC) even if levels of a first reference voltage and a second reference voltage are changed. According to the present invention, the first reference voltage and a maximum feedback voltage are differentially amplified by a first operational amplifier, and the second reference voltage and a minimum feedback voltage are differentially amplified by a second operational amplifier. Furthermore, a feedback voltage generator generates a maximum feedback voltage and a minimum feedback voltage in response to output signals from the first and second operational amplifiers and feedbacks the voltages to the first and second operational amplifiers, such that if the first and second reference voltages are changed, the maximum and minimum feedback voltages are changed to enable the first and second operational amplifiers to output stable signals. A reference voltage generator is operated in response to the output signals from the first and second operational amplifiers to generate stable maximum and minimum reference voltages.
