In nearly 50 years of voltage-feedback amplifier (VFA) introductions, one of the key specifications has been the gain bandwidth product (GBP). Over time, different development groups have delivered ...

Part 1 of this article showed a deviation from theory in using lower bandwidth amplifiers that seems related to the local loop gain collapse around the resonant frequency at F o. Using this to instead ...

TREK, INC. has announced a new high-voltage power amplifier - Trek Model PZD700A - that offers wide bandwidth and additional features important in piezoelectric driving, electro-optics, MEMS and ...

Engineers are frequently faced with the challenge of developing applications to meet a wide range of requirements. Usually, these requirements are difficult to fulfil simultaneously. One example is ...
