    How to determine needed GBW and DC gain of the LDO from spec?

    Hello, Look at the low Freq in the PSRR, its the same as the DC. Regards

    MB1504 PLL locking problems with noise in demodulated output

    mc145170-2 If it's not the surrounding of Loop filter and layout, Did you simulate the PLL? (For phase a Gain margin) It might be on the edge of stability. You can use Pspice for simulation.

    SCts methods calculate the cascode amplifier

    I used this configuration with npn transistors for AMP from DC - to 120Mhz 0-70v output. So, you can take Ce and Cin out but you will have to take care for the DC Bias level - in temeperature etc. The gain will be G=Vout÷Vin ≈ Rd÷Re (from ≈ dc to fc)

    Is +/- 1n PLL jitter performance good?

    Re: PLL jitter pleas note the peak-to-peak cycle-to-cycle jitter is not as good as a jitter accumulation measurement.

    differences between different types of capacitors

    Use this sw to get more info about performences of diffrent capacitors. In general- 1. Electrolytic capacitors - use for low cost, High ripple curent, low ESR and shorter MTBF and high cap value. 1UF and above. use For power s. 2. Polyester capacitors- use for High Stability and Reliability...
