ABSTRACT:
An analog delay element for delaying an input clock signal to produce an output clock signal. The analog delay element includes a delay circuit for receiving the input clock signal and for providing an intermediate clock signal in response to a first bias voltage. A current mirror amplifier generates a first current in a first current branch in response to the intermediate clock signal, and generates a second current in a second current branch in response to the first current and a second bias voltage. The second current branch has an output node for providing the output clock signal having a logic level corresponding to the delayed intermediate clock signal logic level.
