Abstract
The frequency limitation of coupled-biquadratic active ladder structures is derived in terms of the gain-bandwidth products of the operational amplifiers. It is shown that the finite bandwidths of the amplifiers are analogous to finite negative Q factors of the passive inductance-capacitance LC counterpart, and a technique is proposed for the compensation of the passband deviation that is caused by this effect.
