Circuit with voltage drop element

An analog baseband circuit, comprising:

• a programmable gate array (PGA);
• a low pass filter (LPF);
• and
• a driver, which are DC coupled in series,
• wherein each of the PGA, LPF and DRV comprises:
• a circuit comprising:
• a circuit input;
• a circuit output;
• at least one passive feedback loop coupled between the circuit output and the circuit input;
• an active element, coupled in a feed-forward path of the circuit between the circuit input and the circuit output and configured to drive the at least one feedback loop in order to establish a function of the circuit,
• wherein the feed-forward path of the circuit comprises a second node and a first node which are internal nodes of the active element and which are coupled between the circuit input and the circuit output, wherein the first node is configured to have a first voltage, the first voltage being a function of the circuit output,
• wherein the active element comprises a first voltage drop element coupled between the second node and the first node, and
• wherein the first voltage drop element is configured to decouple a DC level at the first node from a DC level at the second node and configured to provide the DC level at the first node independently from the DC level at the second node.
