Classification: H03L,H04L

Abstract:
A differentiation, rectification, mixer circuit comprising:a) a first inverter pulse generator and a second inverter pulse generator for receiving nonreturn-to-zero (NRZ) data and in response thereto generating a signal having a frequency (f); andb) a differential pair coupled to the first and second inverter pulse generators for mixing said signal having a frequency (f) and a clock signal; the differential pair includes:a first transistor having a gate electrode for receiving a clock signal, a drain electrode for providing an inverted output signal, said inverted output signal having a frequency (f), and a source electrode coupled to the output of the first inverter pulse generator and the output of the second inverter pulse generator; anda second transistor having a gate electrode for receiving an inverted clock signal, a drain electrode for providing an output signal, said output signal having a frequency (f), and a source electrode coupled to the output of the first inverter pulse generator and the output of the second inverter pulse generator.
