| Abstract |
| | Concept of introducing special compensating channels in the circuits of differential operational amplifiers (OA) is considered. Their main purpose is reducing OA error, which is caused with the input common-mode signal and an offset voltage. Application of the proposed architectural solutions in practical circuit gives the increase (more than an order of magnitude) of input common mode rejection ratio and noise supply rejection ratio. |
