A multiplexer structure includes a semiconductor substrate having a shared diffusion
region. A first gate having a first finger and a second finger is disposed on the
shared diffusion region, and a second gate having a first finger and a second finger
is disposed on the shared diffusion region. A contact for a first input node is
disposed on the shared diffusion region between the first and second fingers of
the first gate, and a contact for a second input node is disposed on the shared
diffusion region between the first and second fingers of the second gate. A contact
for a collector node is disposed on the shared diffusion region between the first
and second gates. In operation, closing the first gate electrically connects the
first input node and the collector node, and closing the second gate electrically
connects the second input node and the collector node.
