In one aspect of the invention, an analog buffer circuit includes a p-channel field effect transistor (PTFT) and an n-channel field effect transistor (NTFT). Each of the PTFT and NTFT has a source region and a drain region defining a channel region therebetween, formed on a substrate such that the drain regions of the PTFT and the NTFT are in substantial contact with each other, a gate layer formed over and insulated from the corresponding channel region, a source electrode insulated from the gate layer and electrically connected to the corresponding source region, and a common drain electrode insulated from the gate layer and the source electrode, and is electrically connected to the drain regions of both the PTFT and the NTFT through a via defined over the depletion region. |
