Embodiment Construction

[0010] Please refer to figure 1 , figure 1 It is a schematic diagram illustrating the high response speed and long working life buffer 1000 of the present invention. As shown in FIG. 1 , the buffer 1000 includes a buffer circuit 1100 and a buffer driving circuit 1200 . Buffer 1000 is used to convert an input signal V IN buffered to output an output signal V OUT . Due to the input signal V IN The low potential and high potential of can be changed according to the needs of users, so in the present invention, the input signal V IN Only logic 0 and 1 are used to represent the low voltage level and the high voltage level, respectively. while the output signal V OUT The high voltage level is V DD (voltage source V DD provided voltage), the low voltage level is V SS (voltage source V SS supplied voltage). In addition, the voltage source V SS It can be a ground terminal, and the output terminal of the buffer 1000 is coupled to a capacitor C OUT , capacitance C OUT Coupl...

Abstract

The invention provides a method for improving the response speed and prolonging the service life of a buffer. The method comprises the following steps of: detecting an edge of an input signal of the buffer; triggering a pulse signal with a preset time length according to the detected edge of the input signal; and driving the buffer to generate an output signal according to the pulse signal and the input signal.

Description

technical field [0001] The present invention relates to a buffer, more specifically, relates to a buffer, a buffer driving circuit and a method for improving the performance thereof, which improve the response speed and the working life of circuit components. Background technique [0002] In general buffer design, the response speed is limited by the bias voltage of the circuit elements in the buffer. That is to say, if the bias voltage of the buffer is increased, the response speed of the buffer can be accelerated. However, this approach will shorten the working life of the buffer and cause inconvenience to users. Contents of the invention [0003] The invention provides a buffer driving circuit which improves the response speed and working life of the buffer circuit. The buffer circuit includes a transmission transistor and a voltage dividing transistor. The transmission transistor is coupled between a first voltage source and the voltage dividing transistor. The vol...
