... the right side and vice versa. The preceding 10k resitors ensure that neither input can be "shorted" to earth. Amplification of the audio signal is provided by a single stage common emitter amplifier and then via a direct coupled emitter follower. Overall gain is less than 10 but the final emitter f ...

Section C5: Single-Stage BJT Amplifier Configurations
... In the previous discussions, we’ve talked about modes, models and curves of the BJT. So… pretty cool, but so what? Actually, this background was necessary. What we really care about for these devices is what useful functions they can actually perform and, to achieve these useful functions, we have t ...

High Voltage CMOS Amplifier Enables High Impedance Sensing
... error, particularly in higher voltage circuits that involve high resistances. The solution is to use high impedance amplifiers in an electrometer configuration, so only miniscule amplifier input current comes from the test node. To make the input current the lowest possible value, field-effect trans ...

DN132 - Fast Current Feedback Amplifiers Tame Low Impedance Loads
... low impedance loads. This Design Note reviews the capabilities of the LT®1206, LT1207 and LT1210 CFAs and addresses some design issues encountered when using them. These CFAs are fast and capable of delivering high levels of current. They can be readily compensated for reactive loads and are fully p ...

... (i.e., gain vs. frequency plot is that of a single time constant low pass circuit). In the lab, the op-amp was measured to have a DC open-loop gain of 120 dB. The open-loop gain at 10 kHz was measured to be 60 dB. The slew rate is 2 V/µs, and the saturation limits are ±14 V. The input bias current i ...
