Abstract(in English) | We proposed a CMOS multi-scroll integrated circuit consisting of one or more floating-gate (FG) N-type nonlinear conductance circuits, a high-Q active inductor circuit, two capacitors, and a MOSFET resistor. Although the proposed circuit is simple and versatile, the circuit has two disadvantages. 0ne is a large capacitance to obtain a reasonable inductance value from the active inductor circuit. Another is that the floating-gate in the nonlinear conductance circuit entraps charge during fabrication, which shifts threshold voltage of the MOSFET. In this paper, we improve the multi-scroll circuit. In order to achieve the improvement, we apply the quasi-floating-gate (QFG) technique to the nonlinear conductance circuit. As a result, we can avoid the problem introduced by entrapped charge in the floating-gate MOSFETs. Moreover, we modified the active inductor circuit. Consequently, the capacitance value in the improve active inductance circuit is one tenth as large as that in the former circuit to obtain the same inductance. Therefore, we can realize a more compact multi-scroll circuit than the former circuit. |
