Abstract :
Economical active realizations of low-Q, all-pole, low-pass transfer functions are presented. The realizations allow a unidirectional sequence of functional tuning by trimming only resistors. Also, they have low sensitivities to the passive element variations. Experimental results verified the ease of tuning, the low sensitivity, and the low dependence on temperature and power supply variations.
