ACTIVE HIGH-FREQUENCY RC FILTER Russian patent published in 2000 - IPC

FIELD: radio engineering; selective radio electronic (microelectronic) devices. SUBSTANCE: filter has operational amplifier 1, first, second, third, and fourth resistors 2, 3, 4, 5, first capacitor 6, fifth resistor 7, second capacitor 8, and additional resistor 9. Such design enables independent non-iterative frequency adjustment of pole w_p followed by attenuation of pole d_p and only by raising resistances of first and second, third and sixth resistors 2 and 3, 4 and 9, respectively. EFFECT: reduced adjustment time, improved yield in microelectronic and hybrid film versions. 2 dwg
