Ultrasonic diagnostic apparatus |
摘要 |
For the purpose of reducing the size and power consumption of a power source in an ultrasonic diagnostic apparatus, charge pump circuits are connected to a transmitter power source. A regulator in the transmitter power source drives the charge pump circuit to generate a positive bias voltage +HV2 higher than a positive voltage +HV1 generated by the transmitter power source. The regulator in the transmitter power source also drives the charge pump circuit to generate a negative bias voltage -HV2 lower than a negative voltage -HV1 generated by the transmitter power source.
