Passive compensation of op-amp VCVS and weighted summer building blocks

By general analysis of the passive compensated operational amplifier (op-amp) inverting voltage controlled voltage source (VCVS) proposed by Wilson, It Is found that the addition of only one compensating capacitor instead of two will result in less phase and magnitude errors. It is found also that the addition of two compensating capacitors has another important application which is the compensation of the op-amp VCVS when looked upon as a generalized three port active building block. Passive compensation of the op-amp weighted summer, when considered as a multiinput VCVS is deduced.
