    • An integrated circuit having an n-channel MOSFET device and a JFET device. The integrated circuit includes a semiconductor layer having an upper surface, an MOS transistor device formed in a doped well of a first conductivity type extending from the semiconductor upper surface and a JFET device. The JFET device includes a channel region in the semiconductor layer spaced from, and having a peak concentration positioned a predetermined distance below, the upper surface. An associated method of manufacturing includes introducing p-type dopant into the semiconductor surface to form a p-well in which the NMOS device is formed and a source and a drain of the JFET device. N-type dopant is introduced into the semiconductor surface to form an n-type region of the NMOS device below the p-well and a gate region of the JFET device. P-type dopant is introduced into the semiconductor layer to simultaneously form a higher concentration p-type region in the p-well of the NMOS device and a channel region extending between the source and drain of the JFET.

    • A method of testing a semiconductor circuit including a pair of contact pads, a biasing circuit for applying a voltage to the pair of contact pads, and a sensing circuit for providing a signal indicative of the voltage applied across the contact pads. The method includes determining a voltage gain and voltage offset of the sensing circuit while the biasing circuit is disabled. The method also includes enabling the biasing circuit to produce a voltage across the contact pads and determining, from the resulting output voltage produced by the sensing circuit, an actual output voltage produced by the biasing circuit at the contact pads based on the determined voltage gain and voltage offset of the sensing circuit.
