Other Parts Discussed in Thread: TINA-TI
I am using TLV9052 Dual Opamp as Amplifier and Comparator.
This is a very cost-sensitive system so each and every component matters to us.
If you see my Amplifier Circuit it is not biased properly. Negative half-cycles will not be available. We are not interested in negative half-cycles that is why Amplifier is not biased for negative half cycles.
My amplifier gain is 50.9 and the Bandwidth of TLV9052 is 5Mhz .So according to my Calculation Closed-loop Bandwidth is 100Khz.(5Mhz/50.9). Please correct me If I am wrong.
During the simulation, I can see that Upto 3Khz it is working fine after that Amplifier is not doing any amplification .
May I know why it is happening like this.
Please find the TINA-TI file and O/P waveforms attached.
