Detailed Solution
Download Solution PDFCMRR (उभयनिष्ठ मोड वाला अस्वीकृति अनुपात) को विभेदक-मोड वाले वोल्टेज लाभ (Ad) और उभयनिष्ठ-मोड वाले वोल्टेज लाभ (Ac) के अनुपात के रूप में परिभाषित किया जाता है।
गणितीय रूप से, इसे निम्न रूप में व्यक्त किया गया है:
Ad = विभेदक लाभ
Ac = उभयनिष्ठ मोड लाभ
आदर्श रूप से Op--Amp के उभयनिष्ठ-मोड लाभ शून्य होना चाहिए, अर्थात् इसे इन्वेर्टिंग और गैर-इन्वेर्टिंग टर्मिनल दोनों पर सामान्य इनपुट के लिए शून्य आउटपुट प्रदान करना चाहिए। ∴ एक आदर्श Op-Amp का CMRR अनंत होता है।
