    • A reduced area delay circuit and method are disclosed. The delay circuit uses a constant current source and a constant current drain to charge and discharge a capacitor and thus control the delay time of the delay circuit. The constant current source and drain can be implemented using current mirrors formed by configuring MOSFET transistors in a common source configuration. The delay circuit method includes the steps of receiving an input signal, delaying the input signal by using a constant current source or drain in combination with a capacitor, and then buffering the voltage on the capacitor using two inverters. A programmable delay circuit is also disclosed by adding additional pairs of current mirrors to the delay circuit and selectively enabling the pairs to adjust the delay time.
    • 公开了一种缩小面积延迟电路和方法。 延迟电路使用恒流源和恒流漏极来对电容器进行充电和放电,从而控制延迟电路的延迟时间。 恒流源和漏极可以使用通过在共同的源配置中配置MOSFET晶体管形成的电流镜来实现。 延迟电路方法包括以下步骤:接收输入信号,通过使用恒定电流源或漏极与电容器组合来延迟输入信号,然后使用两个反相器缓冲电容器上的电压。 还公开了可编程延迟电路,通过向延迟电路增加额外的电流镜对,并且选择性地使得对可以调整延迟时间。
