Abstract:This paper proposes square-root-domain currentmode first order inverting and non-inverting all-pass filters. The proposed filters are designed by using state-spacesynthesis method with current-mode square-root circuits, squarer/divider circuits, current mirrors, current sources and grounded capacitors without any external resistors. Therefore, the proposed filters are appropriate to develop into an integrated circuit. The center frequency can be adjusted electronically by changing the values of the external cu… Show more
