VOLTAGE-CONTROLLED OSCILLATOR AND BIAS GENERATION CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18546172 titled 'VOLTAGE-CONTROLLED OSCILLATOR AND BIAS GENERATION CIRCUIT

Simplified Explanation

The voltage-controlled oscillator described in the patent application consists of multiple unit cells connected in parallel with transmission lines and an input termination resistor. Symmetrical voltages are supplied to the unit cells, and a compensation unit cell is used to compensate for any gain discrepancies between the unit cells.

  • The voltage-controlled oscillator includes a first unit cell, a second unit cell, and a compensation unit cell connected in parallel.
  • Symmetrical voltages are supplied to the first and second unit cells.
  • The compensation unit cell compensates for any gain differences between the unit cells.
  • An input termination resistor is connected to the power supply voltage terminal of each unit cell.

Original Abstract Submitted

A voltage-controlled oscillator includes a first unit cell, a second unit cell that is connected in parallel to the first unit cell via transmission lines, a compensation unit cell that is connected in parallel with the first unit cell and the second unit cell between the first unit cell and the second unit cell, and an input termination resistor that is connected to a power supply voltage terminal of each of the first unit cell, the second unit cell, and the compensation unit cell. Symmetrical voltages are supplied to the first unit cell and the second unit cell, and the compensation unit cell compensates for a gain by the first unit cell or the second unit cell.
