1 kHz to 30 MHz Oscillator using only Three Components
Building a square-wave oscillator using only three components is always a desirable accomplishment when space is tight, and if you can achieve a frequency range of 1 kHz to 30 MHz at the same time you have a component that can be used an a wide variety of applications.The Linear Technology LTC1799 (www.linear-tech.com/pdf/1799f.pdf) is the first IC that can manage this feat. It needs only an external resistor RSET to set the output frequency.
