为了提高显示屏的成品率,降低成本,提出了一种由全p沟道TFT构成的屏上驱动电路。基础电路部分包括反相器和移位寄存器,屏上驱动电路主要是行驱动电路和列驱动电路。行驱动电路和列驱动电路基本上都是由反相器和移位寄存器构成,全部采用p-TFT来构成驱动电路。该驱动电路工作正常,能够实现CMOS驱动电路的功能,驱动OLED器件正常发光。通过仿真验证和理论分析表明该驱动电路不仅性能稳定而且成本低、成品率高、外接引线少及外围驱动电路复杂性低。 相似文献

This paper presents a new gate turn-off drive circuit for GTO thyristors, which can accomplish faster turn-off switching for high-speed operation of the GTO. The switching characteristics of GTO's can be improved by use of the gate drive circuit that is able to make a very high rate of the negative gate current. The major disadvantage of the conventional gate turn-off driving technique is that it has a difficulty in realizing higher negative diG/dt due to the maximum reverse gate-cathode voltage and the stray inductances within the gate turn-off drive circuit. This paper shows that this problem can be overcome by adding another gate turn-off drive circuit to the conventional gate turn-off drive circuit. Simulation and experimental results in conjunction with chopper circuit verify the performance of the proposed gate drive circuit 相似文献

Novel improved power metal oxide semiconductor field effect transistor (MOSFET) drive circuits are introduced. An anti-deadlock block is used in the P-channel power MOSFET drive circuit to avoid deadlocks and improve the transient response. An additional charging path is added to the N-channel power MOSFET drive circuit to enhance its drive capability and improve the transient response. The entire circuit is designed in a 0.6 μm BCD process and simulated with Cadence Spectre. Compared with traditional power MOSFET drive circuits, the simulation results show that improved P-channel power MOSFET drive circuit makes the rise time reduced from 60 to 14 ns, the fall time reduced from 240 to 30 ns, and its power dissipation reduced from 2 to 1 mW, while the improved N-channel power MOSFET drive circuit makes the rise time reduced from 360 to 27 ns and its power dissipation reduced from 1.1 to 0.8 mW. 相似文献
