Patent number: 11405026Abstract: Embodiments of the present disclosure provide systems and methods of reducing the EMI effect generated by such analog blocks. By varying the clock frequency in time of oscillators used by such analog blocks, the EMI energy may be spread over a wide spectrum range thereby reducing the peak energy for the main frequency. To achieve this, the oscillator frequency is directly varied using analog mechanisms. The mechanisms may be based on a synchronized method for increasing/decreasing the current that is charging/discharging the oscillator capacitor. The frequency variation may be achieved by analog control of the extra charge/discharge current.Type: GrantFiled: January 29, 2021Date of Patent: August 2, 2022Assignee: Infineon Technologies LLCInventors: Oleg Dadashev, Yoram Betser
