Method for indirect measurement of the phase delay of a RF-PWM modulator |
摘要 |
A delay measurement system to measure a phase delay of a Radio Frequency-Pulse Width Modulated (RF-PWM) signal introduced in a Radio Frequency-Pulse Width Modulator, wherein the RF-PWM signal comprises a sampling frequency and at least one carrier period, and wherein the RF-PWM signal has a symbol in the at least one carrier period. The delay measurement system comprises a first phase modulator circuit configured to generate a first Binary Phase Shifted (BPS) signal having a first period and a second period based upon the RF-PWM signal, wherein the first period of the BPS signal has the symbol therein and the second period of the BPS signal has a 180 degree inverted version of the symbol. The delay measurement system further comprises a second phase modulator circuit configured to generate a second Binary Phase Shifted (BPS) signal having a first period and a second period, wherein the first period of the BPS signal has the symbol therein and the second period of the BPS signal has a 180 degree inverted version of the symbol. Further, the delay measurement system comprises a detector circuit configured to determine the phase delay of the RF-PWM signal based on the first BPS signal or the second BPS signal and output the phase delay. |
