Abstract
An analog correlator for very high speed data communication, including a single transmission line receiving an input signal and used as a signal delay circuit, a plurality of analog multipliers connected in parallel with a predetermined gap from the transmission line, for receiving a predetermined size of voltages, respectively, and an adder for adding the signals from the plurality of analog multipliers and transmitting the resultant signal as an output signal. The analog correlator can perform very high speed data communication, and can be applied to a high precision position estimation system. Moreover, the time delay is controlled in each part of the transmission line by adjusting a size of a variable capacitor. As a result, the length of the transmission line can be adjusted. Furthermore, the correlator is adaptively used according to variations of the very high speed communication environment by adjusting voltages of application voltage devices.
