Abstract :
New circuit techniques permitting fabrication of a wide-range monolithic VFO with a frequency stability of ±20 ppm/°C will be described. In addition to its uses as an FM/FSK modulator/demodulator and AM modulator, the circuit can also be used for suppressed-carrier AM and binary phase-shift-keying.
