operational amplifier - Sine Wave Generator Circuit - Bipolar ...
I was wondering what changes to the circuit would be needed to change this circuit to a bipolar (+-5V) I'd start by powering both op-amps with bipolar supplies, something like +/- 9 volts. This gives enough supply overhead to produce a sensible output level of a 5 volt peak sine wave.
What's the easiest/cheapest variable-frequency sine wave …
2010年8月8日 · This circuit includes a configurable frequency generator (5 switches select input frequencies from 1/16 of the input up to 31/16 of the input). I also threw on a rough square-to-sine converter. Note that unlike most filtering techniques, this one maintains a reasonably consistent amplitude over the frequency range.
operational amplifier - 10MHz Sine Wave Generator - Electrical ...
I have been looking for some time for a good design for a ~10MHz sine wave generator, with variable frequency from about 5-20MHz. The max required peak to peak amplitude is 10V. Many suggestions on the internet include using DDS such as …
filter - How to build a circuit that generates a sine wave ...
2016年4月7日 · How can I build a circuit to generate sine waves? What I am working on is building a 555-timer circuit that gives 50% duty cycle square wave, then using a low-pass or band-pass filter tuned to the frequency of the square wave to get a sine wave from the square wave (because square wave consists of infinite number of sine harmonics).
How can I drive an LC tank circuit to get a nice and clean sine wave?
2020年12月22日 · This generated following source to drain switching wave form. Although its not a perfect sine wave (yellow) yet its very much clean from ringing noise. Blue signal is received at Rx. Following is the signal across tank circuit. The vpp at yellow signal is 1.64V only. To increase to signal strength i removed 47ohm resistor between supply and tank.
Generating high frequency sine wave (up to 100MHz)
2020年7月14日 · This generator should be able to sweep through a range of frequencies and the range would be 150 KHz to 80 MHz. the sweep rate is not more than 1.5*10^-3 decades/s. There are different oscillator topoplogies, but I can't use, say a purely RC oscillator or a crystal oscillator as they offer a static method of generation (single frequency).
From sine wave to square wave - Electrical Engineering Stack …
2021年6月23日 · I want to make a square wave generator with an LM311. I have a variable sine wave source from 1Hz to 16kHz. The amplitude can vary between 0.5V to 11.4V. I tried to use the comparator circuit below but couldn't get an acceptable result. Sine wave configuration: Blue is the output of the comparator, yellow is the sine wave:
Constructing a sine wave generator circuit using LTSpice
2021年2月12日 · \$\begingroup\$ Also note that in the real world, an oscillator starts on noise and/or small imbalances in the circuit. These are (usually) not present in a simulator, everything is more ideal. That often means that the simulator won't start the oscillation. Solve that by injecting a current pulse at some point in the circuit.
How to design a cheap sine-wave generator up to 200 MHz?
2016年10月28日 · If you are prepared to use switched banks of filters you might as well consider using switched banks of colpitts sine wave oscillators. One transistor will get you a decent enough sinewave and add a couple of varactor diodes and you get a simple dc voltage control of frequency over a range greater than 2:1 i.e. one colpitts circuit gives you ...
1Hz Sine wave oscillator - Electrical Engineering Stack Exchange
2018年3月28日 · The sine wave in the design is heavily distorted, and it's difficult to measure the actual frequency - The frequency counter doesn't show anything (I'm assuming it's because the frequency is too low, or the waveform is too distorted), and the oscilloscope doesn't plot the wave for long enough for me to calculate frequency manually (by measuring ...
