pmos wide swing current mirror
typical wide swing cascode is shown below. (Fig A)
some wide swing cascode circuit uses pmos instead of nmos.
example is shown below. (Fig B)
Pmos is used as diode connected nmos. however I don't know how it works exactly. Is it Possible to use pmos is not connected drain & gate terminal ?
How can you say pmos is diode-connected mos?
in additional, I want to know what is disadvantage & advantage about Fig B circuit.
thanks
