It pioneered active base current cancellation and offset trimming, using Erdi's patented Zener-zapping technique. Erdi and other PMI engineers later expanded their efforts to include high-precision voltage references and additional mixed-signal semiconductors for data acquisition, data conversion, and telecommunications.
This innovation introduced advanced base current control and offset fine-tuning, employing Erdi's patented Zener-suppression technique. Later, Erdi and other PMI engineers expanded their work to include accurate voltage references and additional mixed-signal components for data processing, transmission, and communication.
