摘要:
The Dauphinee‐Mooser circuit has been improved by incorporating into it a transistorized null detector. The effective noise level has been cut down to, and possibly below, the chopper noise level by picking only the portion of signal that is observed while the contacts are closed. Pickup of external stray signals has been cut down to the level where they are virtually imperceptible. A complete description of the amplifier circuit is included.
