  • Voltage controlled oscillator for recovering data pulses from a data input stream having digital data with an unknown phase
    Patent number: 6040743
    Abstract: A voltage controlled oscillator (VCO), for use in a phase locked loop for clock multiplication, for example in recovery of data pulses from a data stream input comprising digital data with unknown phase. According to the invention, the VCO comprises a plurality of VCO stages, each stage being implemented as a differential amplifier. The amplifier load is formed of two cross-coupled gate devices and of two gate devices which are connected as diodes. The differential input is applied to a source coupled input pair as well as to two pull-down gate devices.
