A circuit comprising:
- an amplifier having an input and an output;
- and
- at least one transistor formed on at least one substrate, the at least one transistor comprising:
- at least one terminal;
- and
- at least a first well and a second well;
- wherein the at least first and second wells are electrically isolated from the at least one substrate;
- wherein the at least second well is electrically isolated from the at least first well;
- wherein the second well is separated from the substrate by the first well;
- wherein the input of the amplifier is electrically connected to the at least one terminal of the transistor;
- and
- wherein the output of the amplifier is electrically connected to the at least first well of the at least one transistor, thereby biasing the first well with a signal proportional to a signal present at the at least one terminal of the transistor.
