2-5V, 2-4mW, 3차 타원 저역통과 Gm-C 필터
2-5V, 2-4mW, the third-order Elliptic Low-pass Gm-C Finer
초록
In this paper, a Gm-C filter for low voltage and low power applications using a fully-differential transconductor is presented. The designed transconductor using the series composite transistors and the low voltage composite transistors has wide input range at low supply voltage. A negative resistor load (NRL) technology for high DC gain of the transconductor is employed with a common mode feedback (CMFB). As a design example, the third-order Elliptic lowpass filter is designed. The designed filter is simulated and examined by HSPICE using 0.25
