摘要： A single-chip common-drain JFET device comprises a drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

摘要： Electronic circuits use low-cost depletion-mode JFET to serve as power switch. Since depletion-mode JFET has smaller conductive resistance and is majority carrier device, the energy loss is less when current flows through the depletion-mode JFET, and faster switching speed is obtained, thereby enhancing the efficiency of the electronic circuits.
