  • CR4 - Thread: Circuit Wanted: Half-Wave Signal Generator
    Use a monostable / multivibrator with clear to drive the VCC input at the top of R3. You'll need one more op amp (in comparator mode) to detect the bottom of the ramp and clear the monostable.
  • Negative resistance curve tracer
    The op amp IC, is used as a zero-crossing detector. The output pulses of the zero-crossing detector are used as triggers for the monostable multivibrators IC, and IC,. The negative output pulses of IC, will be clipped by diode D13.
  • Single OTRA-based current-mode monostable multivibrator with two triggering modes and a reduced recovery time
    The current-mode monostable multivibrator previously proposed in [10] comprises a single OTRA and four passive elements (two resistors, one capacitor and one diode). This circuit is more compact than the traditional op amp -based approach, which requires one more external resistor. In order to shorten the recovery time, a novel top- ology that uses an analogue switch to …
  • Detection of imaging acoustic signals for synchronizing a commercial ultrasound imager with a high intensity focused ultrasound therapy system
    Next the signal is amplified with a noninverting op - amp with 6 dB of gain (National Semiconductor LM7171) and sent to an n-channel MOSFET (ON Semiconductor 2N7000), where the output is limited to maximum amplitude of 5 V across a source … This is done to protect the monostable multivibrator timing chips (Texas Instruments SN74121) in the pulse generator module that creates the control signals for phasing and gating the HIFU burst. Time constants from capacitor/potentiometer pairs are used in conjunction with the timing chips to manually adjust phasing …
  • A hybrid digital and analog controller for DC and brushless servomotors
    Op - amp A2 forms a conventional differentiator to provide the derivative component, as well as the proportional component, of V,, . As explained in the previous section, the analog loop is effective only in the static state. To discriminate between the dynamic and static states, the circuit shown in Fig. 9 is used . The retriggerable monostable multivibrator (MM) compares the period r8 of the serial position command with the time T,,determined by RTCT.
  • A stable electrometer amplifier for space-borne instruments
    A monostable multivibrator of 100 ms duration is used to switch the FETS on and off and trigger the DC sweep generator. The 741 op - amp has been introduced to increase loop gain and negative feedback.
  • Current Conveyors
    When used in negative feedback, the infinite transresistance gain Rm forces the two inputs current to be equal-a property which can be considered to be the dual of that available in a voltage- mode op - amp . Due to these advantageous features, the OTRA has been employed extensively in realizing immittance simulator topologies, Schmitt trigger, monostable /bi-stable multivibrators , sinusoidal oscillators and SRCOs, for instance, see references [23–26] and those cited therein.
