  1. Closed: Re: simulating the open loop gain of fully differential amplifier fwith open loop set

    I don't believe so. Most people are simulating open loop gain in an intelligent setup, using some kind of DC feedback that doesn't affect the AC gain. That's not so simple in hardware but very easy...

    Closed: Re: PIC serial port receive Problem, please help

    That's a bit more of information.

    1. There may be a hardware problem, e.g. wrong or incomplete connection of the modem module, missing handshake lines etc.

    2. In any case, it's useful to think...

    OERR means overrun error, a new character arrived before the UART buffer has been read. Apparently your code isn't able to process the data in time. Did you consider an interrupt driven RX ring...

    Closed: Re: Cannot get the code of Sensorless BLDC ESC

    The instruction j -= 1 is effectively pausing the loop to wait for a certain event.

    Can cause an endless loop in case of unexpected hardware behavior. That's really bad coding style, I'm not...

    Can we please clarify the post #4 question. What's the oscillator type and has it really low output voltage in the 100 mV range, or even less?

    Closed: Re: Closed Loop Transfer function in Cadence

    So is your question.

    It's not clear at all how closed loop transfer function is related to PLL jitter. If you are asking about a specific analysis type like PAC, you should mention it.

    How do you determine that the design is not "working"?

    How is the shown code used on the board, is test the top design and how is start generated? What's the clock frequency?

    Did you verify...

    To understand the basic amplifier operation, you can place a high ohmic resistor instead of the diodes.

    I expect that the "finger test" adds in the first place losses rather than capacitance. As long as you don't monitor transmission along with reflection, the result is almost useless.

    What is input signal in your circuit? How do you measure it? How should the problem be related to uA733?

    I don't see it in the TL dimensions. You have completely different dimensions in lower and upper branch.
  13. Closed: Re: Adding a 3 band equalizer to a phantom powered electret mic amp

    This sounds all quite strange. If you don't have a suitable professional microphone for comparison, can't you loan a known good condenser microphone from a collegue?

    Closed: Re: How can Transmission line does not see Stub?

    What do you mean with "short circuit"? A short (reflection factor = -1) would reflect the wave back to the input. An absorber port should have 50 ohm impedance.

    The TL width settings look arbitrarily wrong. What are the intended port impedances?
  17. [SOLVED]Closed: Re: Can you please explain how this N-Channel JFET with Diodes work?

    The diodes may be also used as replacement for a high ohmic bias resistor, e.g. in an electret microphone or pyroelectric IR sensor amplifier.

    Closed: Re: How can Transmission line does not see Stub?

    That's hardly possible with this circuit.

    Sounds like you want a SPDT switch (at least two pin diodes) instead of a SPST. It's however not clear what's in- or output in your circuit.

    The purpose of the circuit isn't quite clear.

    First, point, you get impedance mismatch and reflections at Tee1 if the diode is turned on.
