Abstract
A novel internal-node waveform probing technique has been demonstrated on a C-band monolithic microwave Integrated circuit (MMIC) power ampl ifier. The error of the measurement and its perturbance to circuit ope ration was estimated and verified to be within +/-10%. Valuable insigh t was obtained from the variation of waveforms as a function of freque ncy, drive and location, The potential impact of this technique includ es MMIC design verification, in-situ device model extraction, process diagnosis, and reliability assessment.
