Abstract:

Darlington pair amplifier in CC/CE configuration is a useful amplifier circuits for low voltage signals. First time we have proposed two distinct modifications in CC/CE Darlington pair amplifier by replacing one of the BJT of pair from FET and by including an extra biasing resistance RP. We observed that one amplifier produce high voltage gain with improved bandwidth while another produces extremely wide bandwidth with consistent voltage gain. Such amplifiers with distinct behavior may be very useful for amplification of small signals in mid frequency or wide frequency bands.
