Digital logic circuits operate by means of a global sequencing element commonly known as \'clock\'. Error-free operation is assured by operating the clock slower than all circuits, known as synchronous logic circuits. The clock synchronizes all logic circuits.
In contrast, the worst-case condition for printed circuits is the difficulty to model due to distributed and potentially degrading device parameters. Principle challenges of printed electronics are:
i) poor stability of printed circuits as printed transistor parameters degrade
ii) digital circuits incurring large margins due to large distribution of printed transistor parameters
These problems limit the potential of printed electronics to be used in applications that required more integrated functions.
This invention exploits digital asynchronous logic to overcome the problem of degradation and/or large distribution of transistor parameters for more robust printed circuits. The delay of every circuit is correlate with a printed delay circuit, known as matched delay.
Advantages of the asynchronous logic:
