Other Parts Discussed in Thread: TINA-TI
Hi TI experts,
The simulated noise density spectrum is quite different from that shown in datasheet (Fig. 13). The .TSC file is attached below. In addition, I used "select control object" function and set Css to be 0n, 1n and 10n, respectively, as stipulated by datasheet, but the simulated traces are identical, indicating that Css has no effects on output noise.
Furthermore, when simulating noise performance, why do I have to use a current generator as an input instead of a curent source, which is not allowed by TINA-TI?
