High_stability_linear_regulator

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

The load and line regulation of this circuit is better than 0.001%.Noise, drift, and long-term stability are determined by Zener D1. Noise can be reduced by inserting 100-kΩ resistors in series with both inputs of the LM108A, and bypassing the noninverting input to ground. A 100-pF capacitor between the LM108A output and the inverting input prevents frequency stability. Temperature drift can be reduced by adjusting R4 for minimum drift. For best results, remote sensing should be made directly to the load terminals, as shown.   (View)

DIFFERENTIAL_TRANSFO_RMER_TRANSDUCER

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

Detects and responds with 0.1% linearity to core displacement. Low-level ac transformer output is converted to 10 to 50 ma d-c transmission signal with : w maximum power by high-input-impedance feedback amplifier. Precision exciter consists of constant-voltage 1-kc oscillator and high-Q swamping choke. Gain is stabilized by using separate d-c feedback loop for each group of d-c coupled transistors.-L. H.

Very_wide_range_V_F_converter

Published:2009/7/23 23:18:00 Author:Jessie

Fig. 12-4 This circuit is a highly modified version of the circuit in Fig. 12-3 and it features a range from 1 Hz to 30 MHz. The circuit maintains a 0.08% linearity over the entire range with a full-scale drift of about 20 ppm/℃. Zero-point error is 0.3 Hz/℃ (and is directly related to the 50 nV/℃ drift specification of the LTC1052). To trim, ground the input and adjust the 1-Hz trim until oscillation just starts. Next, apply 3.000 V and set the 30-MHz trim for a 30.00-MHz output. Repeat the procedure until both points are fixed. Linear Technology Linear Applications Handbook 1990, p AN9-15.   (View)

DIGITAL_SERVO_MODULATOR

Published:2009/7/23 23:20:00 Author:Jessie

Used to subtract two analog currents of digital-to-analog converter, giving phase-sensitive 60-cps square-wave output signal. Modulator is driven from 60-cps line to maintain precise phase relationship with two-phase servo motor. Modulator gives 2.4.mV p-p output signal for 2-microamp input signal on one side, and 1.1 V pp for 1-ma input signal on one side. First output corresponds to least significant digit error in Gray-to-binary converter, and latter to most significant digit error.-Texas Instruments Inc., Transistor Circuit Design, McGraw-Hill, N.Y., 1963, p 492.   (View)
