| Abstract: | In order to improve the range and sensitivity of ultrasonic parking sensor systems,a PROTEL software was used to simulate and select the charge amplifier.We focused on the analysis and simulation experiments aiming at the performance of the charge amplifier circuit formed by four common operational amplifiers with different properties—LM2904,OP07,LF356 and LF357_NSC with a final conclusion of the most suitable charge amplifier circuit for this amplication.The experiment data shows that the circuit based on the actual measuring distance can reach 6 m with an error of 0.6%. |
