50_kHz_BANDWIDTH
Three transistor pairs in CA3600E array are parallel-connected with output stage of CA3130 bipolar M0S opamp to boost current-handling capability about 2.5 times. Use of feedback gives closed-loop gain of 48 dB. Typical large-signal bandwidth is 50kHz for 3 dB down-″Circuit ldeas for RCA Linear ICs、″RCA Solid State Division、Somerville,NJ,1977,p 12   (View)

VARIABLE_BIPOLAR_CLAMPING

Published:2009/6/29 1:37:00 Author:May

VARIABLE_BIPOLAR_CLAMPING
Precision comparator provides independent regulation of both output voltage limits without connection to comparison inputs. A2 and A3 are complementary precision rectifiers having independent positive and negative reference voltages, with both rectifiers operating in dosed loop through A1. A2 senses positive peak of Eo and maintains it equal to +Vclamp by adjusting voltage applied to D1. A3 and D3 perform similar function on negative peaks. Feedback network around output stage of A1 regulatesoutput voltage independently of inputs to A1. —W. G. Jung, IC Op-Amp Cookbook, Howard W. Sams, Indianapolis, IN, 1974, p 228-229.   (View)

200_ns_sample_hold

Published:2009/7/25 0:07:00 Author:Jessie

200_ns_sample_hold
This circuit features an acquisition time of less than 200 ns, a common-mode input range of±3 V, drop of 1μV/pts, hold step of 2 mV, hold settling time of 15 ns, and feedthrough rejection much greater than 100 dB. To calibrate, ground the input, repetitively pulse the sample/hold command line, and adjust the 1-kO pot for 0-V output.   (View)

Analog_multiplier
This circuit shows an LTC1043 (Fig. 1-4B) connected to form a high-precision (0.01%) analog multiplier. The LTC1043 clock is common to both sections, so the X and Y inputs are synchronized. To calibrate, short the X and Y inputs to 1.7320 V and trim for a 3-V output.   (View)

Solid-state capacitor-discharge ignition system improves combustion efficiency by increasing spark duration. For 8-cylinder engine, normal CD system range of 180 to 300,ttS is increased to 600 ps below 4000 rpm the discharge lasts for one cycle or 300 pts because at higher speeds the power cycle has shorter times. Circuit uses 555 timer M1 as 2-kHz oscillator, with Q1-Q3 providing drive to Q4-Q5 and T, for converting battery voltage to about 400 VDC at output of bridge rectifier. When dis-tributor points open,Q7 turns on and triggers M2 connected as mono that provides gate drive pulses for SCR. Article describes operation of circuh in detail and gives waveforms at points a-i.-C. C. Lo, CD lgnition System Produces Low Engine Emissions, EDN Magazine, May 20, 1976, p 94, 96, and 98.   (View)
