oscillator

Hello, It's my first post. I'm new in electronics fields. I'm french and my english is not very good, excuse me. I want to make a VHF oscillator(~ 30 MHz) that his frequency can change with the value of the capacitance. I found in an another post the RF2506 which seems to works but it's...

I am new to LTSPICE and have been experimenting with designing with op amps as filters and oscillators I recently came around this circuit of a "squarewave oscillator" in LMx58 Datasheet and with an aim to replicate it i decided to use an op amp in the LTSPICE viz. LT1007 to create a similar...

Hello, I am trying to simulate a 32.768 kHz Pierce oscillator. I am referencing this particular crystal https://support.epson.biz/td/api/doc_check.php?dl=brief_FC-255&lang=en I believe my values are correct, however, the peak frequency of the FFT is almost only depended on the td value of the...

Hi, I was looking since some days for a schematic to build a sawtooth and triangular wave generator, then I found this schematic on an online simulator: https://www.falstad.com/circuit/e-555saw.html (I report the original link, obviously, to give credits to the person which has made this...
