    Abstract: 本文在研究將傳送進體內的直流電壓轉換為一高壓脈波
    以驅動血液幫浦。此驅動電路之架構由環式震盪器、相位不重
    疊時脈產生器、電荷幫浦以及電位轉移電路所組成,並使用低
    壓降穩壓器(LDO)降低電壓源雜訊。首先,在比較各式電荷幫
    浦電路之後選用一適當的電荷幫浦來設計高壓脈波驅動電
    路,且在考量驅動電路對低壓降穩壓器的影響下對其架構做最
    後修正,另外在因應驅動電路應用之下設計一新型電荷幫浦,
    藉由此新型電荷幫浦發展出另一種高壓脈波驅動電路。
    This thesis focuses on driver which converts, inside human
    body, DC voltage into a high-voltage pulse for driving blood
    pump. The structure of the driver is composed of ring oscillator,
    nonoverlapping clock generator, charge pump and level shifter,
    and it uses low dropout regulator (LDO) to reduce noise from the
    voltage source. First, after comparing strengths and weaknesses of
    some charge pump circuits, a suitable charge pump is chosen to
    design high-voltage pulse driver. Then, the structures are modified
    taking the drivers’ influence on LDO into consideration. Second,
    a new charge pump is designed for converting DC into
    high-voltage pulse. In addition, this charge pump is designed to
    re-develop a new high-voltage pulse driver.
