Apparatus for generating phase shifted clock signals |
摘要 |
Clock phase shifting circuitry includes a cascade connection of inverting amplifiers for generating a plurality of relatively delayed clock signals. Buffer amplifiers couple alternate ones of the inverting amplifiers to a clock phase selection circuit for providing a desired one of said plurality of delayed clock signals. A capacitor is coupled between the output of each inverting amplifier and a point of constant potential. Respective circuits, having an input impedance which emulates the input impedance of the buffer amplifiers, are coupled to the output connections of the inverting amplifiers located between said alternate inverting amplifiers.
