    how to get the PSRR of the bandgap by hspice simulation?

    hspice psrr how about the following ? .... vdd 1 0 sin(3 0.1 100k) ... .tran 1n 100u .probe v(*) i(*) end

    how can design the ptat ?

    maybe i need to choose one vbg add bias circuit to get a good current source , the ptat changed too much with the temperture !!!1

    how can design the ptat ?

    now ,i got a value 50 which do not change too much with the power, but it change a lot with the temperture, such as it change from 40 to 70u when the temperture change from -25 to 125, why ?
  11. Q

    how can design the ptat ?

    hello: how can decide the parameters of the mos-transistor? the circuit schematic is in the razavi's book "the design of analog integrate circuit" page 325, 11.31(b) . i want to get a 50uA , i got the value , but the value change a lot when i choose the different power such as when i...

    how to find the phase_noise of one vco?

    but i have no the simulator :spectre_RF ? is there any other ways ? if i can simulate some other parameter using the hspice ?

    how to convert the hspice_model into spectre_model?

    thank you !!! but , i have chosen the spice netlist in the ade envirment, and i have run the spp -convert hspcompitible <><> in the console, but it does not work still ,?why?
  15. Q

    how to convert the hspice_model into spectre_model?

    now ,i have the hspice model , but i want to use the spectre to simulate again, how can i convert it into spcetre ? thank you first!!
