The demonstration of the first integrated circuit using monolithically inte
grated InAs/AlSb/GaSb resonant interband tunnelling diodes (RITDs) and InAl
As/InGaAs/InP high electron mobility transistors (HEMTs) is reported. A D-f
lipflop (D-FF) was implemented using the monostable/bistable logic element
(MOBILE) circuit architecture, with a measured effective voltage gain in ex
cess of 380. Power dissipation of less than 2.8 mW/gate was measured.
