    low noise frequency amplifer using advance design system

    I need to design a low noise amplifier operating between 890MHz – 910MHz using an Infineon RF transistor BFP640. Can someone post a tutorial that might be helpful for starters

    PLL demodulator circuit

    R1=330k,R3=100k,Rs=100k,c1=1.5nF,C2=560pF I got some wierd signal at the demodulator output. signal at the middle is static, and the others are vibrating. pls some help me

    Problem with phase comparator output in a PLL circuit

    I have built a PLL ciruit but I dont whether the circuit working properly or not. The output to the VCO seems to behave well. But when I check the Phase Comparator output the signal is not a DC signal. Help me please anyone. p/s I did not use any fitler

    phase lock loop problem

    i have read some application note on this. but still the circuit does not work. Added after 2 minutes: the phase comparator output should be a dc straught line right? but i get some pulse on it.

    phase lock loop problem

    i'm built a circuit using mm74hc4046. i'm connected 4.5 vdd. r1=330k,r2=330k,c1=3.3nF for the VCO. i got 15kHz for the VCO center frequency. but when i change the input signal to what ever frequency. the output still showing the same thing. pls some one help me.

    phase lock loop design using 74hc4046

    phase lock loop design. im designing a phase locked loop as a FM demodulator using 74hc4046. Can anyone explain to me what expected output at the output of phase detector and VCO. The output signal that I get from VCO is exacly the same as the input signal. but oscilloscope show nothing at the...

    analog vs digital phase locked loop

    analog vs digital pll can anyone tell me difference or compare between analog and digital phase locked loop. by digital i did not mean all digital pll. only the phase sensitive detector part is digital the system still using VCO.
