| Abstract(in English) | Current Memory cell works as a current sampling and holding circuit. It can accurately memorize an input current independent of element matching because it consists of unit device, although accuracy of current mirror based memory is limited by element matching. However, in a practice, its accuracy degrades due to chanel length modulation effect, charge feed through from switches, and electrical noises generated within the MOSFETs themselves. In this paper we propose a technique for current memory cell which reduce such non-idealities by introducing class AB switching technique. It have been confirmed by HSPICE simulation that charge feed through error and RMS of thermal noise can be reduced to 0.1% and one-fifth, respectively. As an application, algolithmic A/D converter has been designed using 1.5μm CMOS fabrication process. The performances(10bit resolution, 2MHz clock operation, 2.0V power supply, 0.45mW power consumption)are confirmed. |
