Abstract
An apparatus for a current mode logic variable delay element. A preferred embodiment comprises an input signal that is provided to a multiplexer (for example, multiplexer ) in both buffered (via a buffer (for example, buffer )) and unbuffered form. A control signal of the multiplexer may be used to select from either the buffered or unbuffered input signals. By using a control signal at an intermediate value (somewhere in between values that selects the buffered or unbuffered input signals), the multiplexer may then combine the buffered and unbuffered input signals in proportion with the value of the control signal and imparts a delay upon the input signal that may be in between the delay imparted by the buffer.
