Isolation amplification circuit with improved common mode rejection

An isolation amplification circuit comprising:

• an input stage circuitry and a control circuitry stage inter-connected through a galvanic isolation barrier;
• said input stage circuitry being referenced to a first ground potential and configured to receive at least a first electrical signal and a second electrical signal generated by a signal source;
• said input stage circuitry comprising:
• a first filter network comprising a first input node, a first output node and first common node wherein the first output node is configured to supply a first output signal in response to application of the first electrical signal at the first input node;
• and
• a second filter network comprising a second input node, a second output node and a second common node, wherein the second output node is configured to supply a second output signal in response to application of the second electrical signal at the second input node;
• and
• a first feedback path configured for lowpass filtering the first output signal and supplying a first lowpass filtered output signal to the first common node;
• and
• a second feedback path configured for lowpass filtering the second output signal and supplying a second lowpass filtered output signal to the second common node.
