Amplifiers Circuits - Low Noise Schematics

40kHz Light Receiver Amp - This circuit is similar to number 121 but provides more gain and operates up to 40KHz. However it draws more power supply current.

Composite Amplifier Improves Noise  - EDN-Design Ideas:  Amplifying low-signal levels for signal processing often stretches a single op amp's abilities. A composite design can improve the input noise for detecting extremely small signals and can enhance output-drive ability. Both the op amp's noise terms and the thermal noise of the components limit the minimum noise in an op-amp-based design..

Composite Amplifiers - AN21 Linear Technology Applications often require an amplifier that has extremely high performance in several areas. For example, high speed and DC precision are often needed. If a single device cannot simultaneously achieve the desired characteristics, a composite amplifier made up of two (or more) devices can be configured to do the job. AN21 shows examples ....

Low Noise AC Amplifier has Digital Control of Gain & Bandwidth - EDN-Design Ideas: In low-noise analog circuits, a high-gain amplifier serves at the input to increase the SNR. The input signal level determines the input-stage gain; low-level signals require the highest gain. It is also standard practice in

Low Noise Amplifier for Phase Noise Measurements - The phase noise of low noise oscillators and signal sources is usually determined by measuring the audio noise voltage at the output of the phase comparator in a phase-locked loop. The phase comparator is typically a low noise doubly-balanced mixer with a phase slope from a few tenths of a volt per radian to a few volts per radian.

Low Noise Balanced Microphone Preamp - A discrete front end makes this balanced microphone preamp very quiet, and it has excellent noise rejection.  Since the SSM2017 has been discontinued (sad but true), and if you can't get the INA217 this may be the ideal replacement…

Low Noise Microphone PreAmplifier - Simple unbalanced design, suitable for microphones, very low noise

Quasiresonant Converter uses a Simple CMOS IC - EDN-Design Ideas: Figure 1 shows a flyback power supply that has low noise and uses a simple CMOS 4093 IC for its control. The electrical noise of a converter arises mainly when current switches on. Diode recovery and charging parasitic capacitances create high di/dt, which is the main..

Ultra low noise low dropout regulator achieves 6 nV/√Hz noise floor - EDN-Design Ideas: LDO has ultralow-noise output.

Very Low Noise Amplifier - The phase noise of low noise oscillators and signal sources is usually determined by measuring the audio noise voltage at the output of the phase comparator in a phase-locked loop. The phase comparator is typically a low noise doubly-balanced mixer with a phase slope from a few tenths of a volt per radian to a few volts per radian.
