Abstract :
A new high-frequency monolithic voltage-controlled oscillator (VCO) is described that achieves /spl plusmn/60 ppm//spl deg/C temperature coefficient of frequency over 0-75/spl deg/C at center frequencies from DC to 20 MHz. The circuit also exhibits good linearity of voltage to frequency, and excellent triangle output waveform over the whole frequency range from low frequencies to 20 MHz. The circuit is fabricated using an eight mask IC process and has a die size of 65/spl times/50 mils/SUP 2/.
