Cascode amplifier with dynamic body bias and method thereof

A method of signal amplification comprising:

• receiving a first input signal;
• converting the first input signal into a first current directed to a first drain node using a common-source amplifier (CSA) comprising a first MOST (metal-oxide semiconductor transistor) of a first type, wherein a source, a gate, a drain, and a body of the first MOST of the first type connect to a first DC (direct current) node, the first input signal, the first drain node, and a body voltage, respectively;
• relaying the first current into a second current directed to a second drain node using a first common-gate amplifier (CGA) comprising a second MOST of the first type, wherein a source, a gate, and a drain of the second MOST of the first type connect to the first drain node, a first gate voltage, and the second drain node, respectively;
• adjusting the body voltage using a third MOST of a second type configured in a common-source amplifier topology to receive an AC (alternate current) coupling of the first input signal and output the body voltage;
• and
• establishing a third drain voltage at a third drain node by directing the second current to the third drain node through a DC (direct current) path and terminating the third drain node with a load comprising an inductor configured to provide DC coupling between the third drain node and a second DC node.
