Unity_gain_inverting_wideband_amplifier

Published:2009/7/23 20:57:00 Author:Jessie

This circuit shows the basic connections in a typical unity-gain inverting amplifier. The use of a compensation capacitor Cc is required for the AN104, unless the gain is fairly high. The AN103 only needs additional external compensation in special cases, such as when used as a noninverting unity-gain follower. Rd in the output circuit improves frequency stability. CF compensates for a pole in the closed-loop transfer function, caused by the input capacitance and feedback resistors. A ground plane is recommended, leads must be short, and Rf should not exceed 5.6 kΩ. Typical bandwidth is 35 MHz, with slew rates of 230 V/μs, into a 330-Ω load   (View)

8080_8224_8228_interrupt_type_interface_for_A_D_converter

Published:2009/7/23 20:56:00 Author:Jessie

This circuit shows an interrupt-type interface for the ADC0808/0809 using a 6-bit bus comparator to decode a read-and-write strobe. Viewed from the CPU, this interface looks like a bidirectional data port where the address is set by the logic levels on the in inputs of the DM8131. When data bits are written to the ADC, the 3 least-significant bits on the address bus define the channel to be converted. The rest of the bits are decoded to provide the START and ALE strobes (Fig. 6-13B). When the conversion is completed, EOC sets the interrupt flip-flop, and (when the data bits are read) the interrupt is complete.   (View)

Shield_or_line_driver_for_high_speed_video_applications

Published:2009/7/23 20:54:00 Author:Jessie

This circuit uses the low input current, high speed, and high-capacitance drive capabilities of the LH0033 to full advantage for high-speed video applications, such as in automatic test equipment. In this circuit, the LH003 is. mounted close to the device under test, and drives the cable/shield, thus allowing higher-speed operation because the device under test does not have to charge the cable.   (View)

AF_DlVlSlON_BY_2_TO_11

Published:2009/7/6 3:03:00 Author:May

Ratio of C2 to C1 determines division ratio, as given in table. When C2 charges to peak point firing voltage of Q2, it fires and discharges C2, so C1 charges to line voltage. Q2 then turns off. Next cycle begins with another positive pulse on base of Q1, discharging C1. Division range can be chanced by utilizing programmable aspect of PUT Q2 and changing ratio of resistances.-R. J. Haver and B. C. Shiner, Theory, Characteristics and Applications of the Programmable Unijunetion Transistor, Motorola, Phoenix, AZ, 1974 AN-S27, p 9.   (View)

JFET_bipolar_cascode_video_amplifier

Published:2009/7/23 20:51:00 Author:Jessie

This cascode circuit provides full video output for the CRT cathode drive. Gain is about 90. The cascode configuration eliminates Miller-capacitance problems with the JFET, thus allowing direct drive from the video detector. An m-derived filter, which uses stray capacitance and a variable inductor, prevents a 4.5-MHz sound frequency from being amplified by the video amplifier.   (View)

WIDE_BANDWIDTH_PEAK_DETECTOR

Published:2009/7/6 3:00:00 Author:May

This circuit can detect the positive peaks for signal frequencies higher than 5 MHz. It yields ±1% accuracy for 400 mV to 4 V pk-pk signal amplitudes on sine, square, and triangular waveforms. The Am685 comparator output increases whenever VIN is a greater negative voltage than VOUT; the high comparator output, in turn, charges C1 in a positive direction. The CA3140 op amp amplifies the C1 voltage with respect to the ECL-switching-threshold voltage (- 1.3 V) developed by diodes D1 and D2. For repetitive waveforms, each cycle boosts VOUT until it equals the peak input value. The peak-detection process is aided by the comparator's open-emitter output, which allows C1 to charge rapidly through R2, but to discharge slowly through R2 and R1. Reducing the value of C1 shortens system-response times. Although the circuit can't detect negative-going peaks, it can be modified to measure the pk-pk value of bipolar signals that are symmetric about ground. To do so, divide VOUT by 2 using two 1-KΩ resistors and feed the comparator VOUT/2 rather than VOUT.   (View)
