    Single Sinus bursts generator needed

    Re: Sinus bursts Yes, I used a comperator for crossing detection. That gives me a clock (clk1) at the sin rate. But i need to synchronize this clock to another clock, clk2, that will determine the burst rate. Lets say i need one burst every 1 msec, clk2 gives me a trigger every 1 msec. but i...

    Single Sinus bursts generator needed

    Sinus bursts hi, I have a sinus generator around 650KHz, 5 vpp. I need to produce a sin burst of exactly 1 cycle (at 650 HZ). The sin should start and end at exactly zero voltage. The circuit should produce a single burst every time it is trigged. I didn't manage to produce nice clean and...

    Sin generator at a freq of 1 MHz, and Vpp of 10-20 volts

    Re: Sin generator Ok. Thanks for the information about the op amp. Can you please send me a circuit of a good oscillator? or tell me what the scillator name is? or any reference to this circuit on the web... Thank's alot, Aviad.

    Sin generator at a freq of 1 MHz, and Vpp of 10-20 volts

    Sin generator Hi, I need to build a sin generator at a freq of 1 MHz, and Vpp of 10-20 volts. I've built a Wein birdge and and used 741 Op Amp. But i got a nice sin only for freq up to 100 KHz. I tried to switch to a AD8042, op amp, that has a better BW, but with no sucsses. I would appreciate...

    Amplifier with supply voltages of 0 and 5 volts.

    I'm trying to build a amplifier for a small signal, aound 2.5 volts. Im using the AD8001 op amp. the signal is about 1 MHz, and of a few mvolts so i need a gain of about 40 db. I've buid the circuits a described at the attached file. First i used -5 and 5 volts as supply voltages for a signal...

    "One shot" monostable

    Hi, I need to implement a special Monostable "One shot". When the circuit is trigged, the circuit needs to switch to high instable state for a certain time-"high time" and then switch to low voltage. If there was another trigger while the circuit was at a high instable state the then the...

    Voltage Amplifier at 1MHz, 40dB

    Thank's for the reply. 1) Are you femilier with such a opamp? With a BW of 500 MHz? 2) Can you send me a link/ add a scheme/ describe this kind of current feedback amplifier circuit? Thank's, Aviad.

    Voltage Amplifier at 1MHz, 40dB

    Thanks for the answer. Actually i'm using a high freq opamp- AD8042, in "clasic" non inverting circuit. Any other ideas?

    Voltage Amplifier at 1MHz, 40dB

    Voltage Amplifier Hi, I need help in designing a voltage amplifier. My input signal is a few mili volts, around 1 MHz, and i need a gain of at least 40db. I tried some circuits but nothing worked well... I will Appreciate any help....circuits, PSpice files or any other ideas... Thanks, Aviad.
