Low_noise_technique_with_parallel_amplifiers

Published:2009/7/23 23:53:00 Author:Jessie

This circuit operates on a statistical noise-reduction technique. Noise decreases by the √N of the number of devices in parallel. For example, for nine paralleled amplifiers, noise would decrease by a factor of three, to about 0.33 nV √Hz at 1 kHz. A potential penalty of this connection is that the input-current noise increases by √N devices.   (View)

Basic_F_V_converter

Published:2009/7/23 23:53:00 Author:Jessie

Fig. 12-19 This circuit produces a 10-V output for a 10-kHz full-scale input (square-waves or pulses). Linearity is about 0.06% at full scale. As is the case with most F/V converters, there is a tradeoff between ripple versus response time. With CFILTER at 1μF, as shown, the output ripple is about 13 mVp-p, with a slow 0.6-s settling time. If CFILTER is decreased, the response time is quicker, but ripple increases by the same factor. An increase in CFILTER produces the opposite results. To trim, set the 5-kΩ gain adjust for 10 V out with a 10-kHz input. National Semiconductor, Linear Applications Handbook 1991 p 1253.   (View)

NONADDITIVE_COMMON_PLATE_MIXER

Published:2009/7/23 23:24:00 Author:Jessie

Plates ore coupled by diode that is nonconducting because plate is at lower potential than cathode. If input pulses are not coincident, negative pulse of sufficient amplitude at either input will appear at output. If inputs are coincident, positive pulse appearing at plate of section A will not appear at output unless of sufficient amplitude to overcome bias established by positive output from section B. Radar video must be applied to input 2, since output of section A must overcome 5-v diode bias,-NBS, Handbook Preferred Circuits Navy Aeronautical Electronic Equipment, Vol. 1, Electron Tube Circuits, 1963, p N4-4.   (View)

Amplifier_with_CMOS_inverter_output_stage

Published:2009/7/23 23:24:00 Author:Jessie

This circuit shows a simple, inexpensive way to extend the output swing of an amplifier to the supply rails. The circuit is particularly useful in 5-V analog systems, where improvements in available output swing are desirable to maximize signal-processing range. As shown by the table, output swing is quite close to the positive rail, particularly at loads below several mA.   (View)

Lock_in_amplifier

Published:2009/7/23 23:19:00 Author:Jessie

carrier-modulated output of the signal source. Because the desired signal information is contained within the carrier, the system constitutes an extremely narrowband amplifier. Noncarrier related components are rejected, and the amplifier passes only signals, which are coherent with the carrier. The amplifier can extract a signal 120 dB below the noise level. The signal source is a thermistor bridge, which detects extremely small temperature shifts in a biochemical microcalorimetry reaction chamber. To trim, adjust the phase potentiometer so that switching occurs when the carrier crosses through zero.   (View)
