摘要： Provided are an on-chip balun, a transceiver using the on-chip balun, and a method for fabricating the on-chip balun. The on-chip balun includes: a first metal winding including a port grounded and a port to which an unbalanced signal is input; a second winding outputting an induced current generated by the first metal winding as two signals having about equal intensity and a phase difference of about 180°; and a ground shield positioned between the first and second metal windings and having a symmetric structure so as to generate a symmetric parasitic capacitance between the ground shield and the second metal winding. The ground shield can be inserted between the first and second metal windings to remove an asymmetrical parasitic capacitance so as to reduce a phase imbalance and a gain imbalance of an output value of the second metal winding. As a result, a highly balanced on-chip balun can be fabricated.

摘要： A PPB-CM communication system and method. The PPB-CM communication system includes a transmitter which splits a symbol period, which is a transmission unit of a communication signal, into at least a pair of parts, inserts a data signal into one of the parts, and transmits a communication signal having the data signal inserted; and a receiver which receives the communication signal from the transmitter and determines bit information of the symbol period according to which part of the symbol period has the data signal inserted, as determined by comparison of energy levels of the parts. Accordingly, a separate threshold is not required to determine the data bit of the symbol period. Thus, the communication signal can be accurately determined. Also, the communication system can be simply implemented without need of a delay line.

摘要： 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.
