摘要：
A new structure of a current-mode LP active filter in CMOS technology, suitable for applications in very low frequency filters is presented in the paper. On the basis of this structure, particular solution of a sixth-order Bessel filter has been designed and tested by SPICE simulations. The main features of this design are; very low cutoff frequency (2.4Hz), very low dissipation power (9nW) and low supply voltage (1V with additional auxiliary supply voltage equal to -1V).
