  • Abstract
    A detailed description is given of the DTCXO designed for mobile telephone system applications for which it is essential to have a narrower channel spacing. The authors have used a polynomial interpolation technique to achieve a DTCXO with a high frequency-temperature stability within ±0.3 p.p.m. The compact (4 cm3), low-power-consumption (15 mW) DTCXO has been developed by using a flat-packaged CMOS gate array in the circuit of the digital unit
