Abstract
A dynamic clock feedback latch includes a feedback path that generates a data value on an output as a function of data inputs in response to a clock input going low and generates a latching value on the output after a delay from the clock input going high. A first transistor pre-charges a node high while the clock input is low. A second transistor provides a drain path for draining the node low from the pre-charged value while the clock input is high. The output controls a third transistor during the delay to drain the node to a low value if the data value is high and to retain the high value if the data value is low. The feedback path generates the predetermined latching value on the output after the delay to cause an inverted value of the data value to be latched onto the node.
