چکیده
In this paper we describe a new architecture of a frequcncy-lo-voltage convcrtcr VVC) :md iLs high frequency intcgrated applications. The circuit is of a rcduccd complexity and its CMOS implcmcnlalion requires a very small area. Besides its small integration arca, thc circuit is vcry fast and has many inlcrcsting high frequcncy applications. This FVC is used to build an integrated high-precision voltage-controlled oscillator that requires a stable reference voltage lo produce a stable output waveform. Two FVCs are also used to build an integrated Crequency-locked loop circuit similar to a phasc-locked loop design, hut with highcr pedormauccs regarding circuit complexity, locking time and frequency dynamic range.
