Title:
調整可能なコーナー周波数を有するＰＷＭデューティサイクルシンセサイザ及び方法
Document Type and Number:
Japanese Patent JP6416077
Kind Code:
B2
Abstract:
A circuit is provided that includes summing circuit for comparing the PWM output signal to the PWM input signal and producing an increment signal if a value of the PWM input signal exceeds a corresponding value of the PWM output signal and producing a decrement signal if a value of the PWM input signal is less than a corresponding value of the PWM output signal. An integrator produces a duty cycle signal by producing an increase in value of the duty cycle signal in response to each increment signal and a decrease in value of the duty cycle signal in response to each decrement signal. A PWM generator produces the PWM output signal in response to the duty cycle signal to cause the duty cycle of the PWM output signal to equal the duty cycle of the PWM input signal with no loss of duty cycle resolution.
