专利汇可以提供Filter unit using capacitor array专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a filtered signal at an output of a matrix arithmetic unit by adequately setting a capacity ratio of capacitors. CONSTITUTION:Switches S11-S1n are normally placed at earth sides and switches Si are sequentially changed over to earth sides at time 1-(n). An input voltage is passed through buffer amplifier 1 and then applied to a capacitor array by way of each switch. At time (j), capacitors C1j-Cnj are charged by input voltage Xj at the time by way of switch S1j. Until next time j+1, switch S1l is switched to the earth side and Si to an integrator 2i side to transfer charges in capacitors C1l- Cnl to capacitors C1-Cn. As a result, the output potential of each integrator increases by C1jXj/Ci. Switch S12' is normally at an input side and changed over to an integrator side right after time equivalent to this switch to transfer charge to the integrator by way of switch Si. Variation in integrator output voltage at this time is represented by C12X2/C1. A coefficient realizing method like this provides the widening of the dynamic range.,下面是Filter unit using capacitor array专利的具体信息内容。
