| Number | Title | Issue Date |
| 6473454 | Rake combiner apparatus using charge transfer element A RAKE combiner apparatus uses a charge transfer element, which can permit a high-precision RAKE receiver to be constructed by a simple circuit structure, has lower consumption power, can allow the finger number to be arbitrarily set within a range of up ... | 10/29/2002 |
| 6381261 | Random pulse type radar apparatus A random pulse type radar apparatus sends out as an output signal a spectrum spread radio wave including a pseudo random signal-less period and receives echoes in this signal-less period to thereby significantly reduce transmission peak power. The random ... | 04/30/2002 |
| 5987491 | General purpose charge mode analog operation circuit A general purpose charge mode, analog operation circuit provides adder, multiplier, divider (D/A converter) and other functions using a single hardware configuration to be used in different modes. A two-dimensional lattice circuit including electrical cha... | 11/16/1999 |
| 5936567 | Parallel charge signal delivery system, and filtering AD converter using the same A data supply method for performing exact operations by a number of operation units receiving a single signal as input is proposed; and a composition of a system provided with both the filter function and the AD conversion function using the same is also ... | 08/10/1999 |
| 5936461 | Charge domain signal filter The object of the present invention is to obtain a charge domain signal filter by composing an digital filter circuit with analog/digital mixed circuit and by introducing the analog processing into the process of multiplication and addition consuming the ... | 08/10/1999 |
