sentences:  It would be several years before any other company could match the Dac-02.Bresee's superior processes, and George Erdi's outstanding design expertise enabled PMI to establish itself as a superior source of linear amplifiers, including operational amplifiers, some of which garnered U.S. patents.By superior layout and circuit design made possible by Bresee's and Khadders superior process uniformity, transistor performance, and surface passivation, Erdi was able to design and achieve breakthrough advances in micro-power amplifiers with both low input offset and 1/f noise voltage, rivaling many chopper amplifiers formerly used exclusively for microvolt input amplifiers.
