Summary:
Device figure-of-merits for digital ICs are derived from analytical delay expressions for emitter-coupled logic and source-coupled FET logic inverters and are compared with the operating speeds of D-F/Fs reported in previous studies. We show that device figure-of-merits for baseband amplifiers are equivalent to those for digital ICs. The validity of device figure-of-merits are confirmed by measuring the bandwidth of the baseband amplifiers fabricated with AlGaAs/GaAs LBCTs.
