Tuned analog network
Abstract
A noninverting, direct current amplifier stage is cascaded into an integrator stage to form a two stage tuned network with a single input junction common to both stages. The network provides independent adjustment of center frequency, bandwidth and voltage gain. The insertion of a positive feedback loop between the stages provides a very narrow bandwidth network. The addition of back to back zener diodes between the common input node and ground converts the network into an oscillator.
