When the input voltage is connected to ground and the input voltage swing is very small, a standard op amp like the LM324 suffices. Referring to Figure 24.3, it can be seen that the pnp input transistors are biased by the emitter current source. If the positive input is connected to gro...

A schematic diagram for Swartzel's op amp is shown below in Figure H-3, which includes a table of values taken from the patent text. Although the context of the patent is an application as a summing amplifier, it is also obvious that this is a general purpose, high gain amplifier, ...
