PHASE LOCKED LOOP CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106441 titled 'PHASE LOCKED LOOP CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME
Simplified Explanation
The phase locked loop circuit described in the patent application includes a reference current generator, a current digital-to-analog converter, and a voltage control oscillator. The reference current generator generates a summed compensation current to compensate for process changes, temperature changes, or power supply voltage changes. This summed compensation current is converted into a control current by the current digital-to-analog converter, which is used by the voltage control oscillator to generate a signal.
- Reference current generator generates a summed compensation current
