Abstract
A method and apparatus for electrically converting a NRZ signal into a RZ signal. A NRZ signal is summed with a phase-aligned clock signal. The resultant summed signal is then passed through a biased PHEMT transistor which has highly non-linear characteristics. The transistor is biased such that portions of the summed signal below a predetermined level are clipped resulting in an inverted RZ format signal equivalent to the received NRZ signal.
