TWO_PHASE_VOLTAGE_CONTROLLED

Published:2009/7/6 3:09:00 Author:May

Produces fixed-amplitude sawtooth outputs that can be shaped to give sine waves, with outputs of the two identical channels differing by a specified phase such as 90o. Each output is integrated to give rising or falling ramp that controls switching FET of opposite channel. With oscillation established, one integrator output goes toward zero and the other away from zero, with same or opposite polarity. When first output crosses zero, discriminator switches FET in input amplifier of other channel, witch action being self-perpetuating to give desired sawtooth outputs. Dashed-line gating at outputs of discriminators can be used to boost slope of one sawtooth in one quadrant.-F. B. Jones, Voltage-Controlled Two-Phase Sawtooth Oscillator, Wireless World, June 1973, p 285.   (View)

Inverting_amplifier_for_gains_greater_than_10

Published:2009/7/23 21:04:00 Author:Jessie

This circuit shows an AH0014 connected as an inverting wideband amplifier, where gain must be greater than 10. If the gain is over 100, Cc can generally be omitted. For best results, use an Rf of 1 kΩ or less (to minimize the effects of stray capacitance). When Cc is in the 10-pF range, a stable gain of 20 dB is possible at 10 MHz. If peaking occurs, tower Cc to the 1- to 5-pF range. Atypical value for CF (when used) is 1 to 5 pF. A typical value for Rd (when used) is 33Ω.Figure 3-48B shows external connections for the AH0014.   (View)

DUAL_TIMER_TONE_STEPPER

Published:2009/7/6 3:08:00 Author:May

One section of RS556 dual timer is connected as free-running astable MVBR for supplying pulses to trigger input of other section connected as mono MVBR driving loudspeaker. When both MVBRs are adjusted so one trigger pulse initiates each timing period and no trigger pulses occur during timing pefiods, output tone has frequency of freerunning MVBR. With two trigger pulses per timing cycle, every other trigger pulse is ignored and tone is at half frequency. With three trigger pulses per cycle, output is one-third of frequency. Can be used for classloom demonstration of electronic music;settings of R1 and R3 can be adjusted to give tones regembling violin, bagpipes, or almost any other instrument.-F. M.

High_gain_video_amplifier

Published:2009/7/23 21:00:00 Author:Jessie

This circuit shows an AH104 used as a high-gain video amplifier. The high output-current capability makes the AH104 suitable for such high-frequency driver applications. In this circuit, a closed-loop gain of 60 can be obtained to 10MHz. For lower gains, Cc must be larger to promote stability. The power connections are the same as for Fig. 3-45. The AN103 can be used in this circuit, without Cc, but the internal 20-pF compensation capacitor reduces the gain at any given bandwidth.   (View)
