Title: Carrier return circuit
Inventor: SU JAU-CHIN
IPC: H04N9/45
Filed: 2000-06-28
Granted: 2002-02-11
Abstract: The present invention proposes a design that uses a pilot signal, which is only added in the residual band edge mode, to complete the entire carrier return circuit. The carrier return circuit is featured with the followings. (1) Only a simple stage of filter is required to filter most of the noise since the maximum frequency error is only 100 KHz after the carrier in the carrier return circuit is demodulated. (2) The completely digital concepts of lead/lag detection and Delta/Sigma FLL are applied in the whole system. (3) The entire system is operated in one stage of phase lock loop such that the system is stable forever. The feasibility is verified through the simulations of C and Verilog, and additionally, the realization is obtained by using TSMC 0.35 μ process and the read only memory (ROM) provided by CIC. The entire circuit uses only more than 3000 logic gates (ROM is not included) such that hardware complexity can be greatly decreased and, additionally, layout area is very small. Furthermore, the phase noise is about 6 degrees.
