Hi everyone,

I have to design an universal amplifier with 0.5 um cmos technology...It should function as
1)VCVS
2)VCCS
3)CCCS
4)CCVS

i have to accomplish this for min. of 100 unit gain with one ckt and i can use switches to get various outputs as needed..

can someone help???


thanks in advance....

Hi evryone,

Giving you the complete details...


a Universal Amplifier block so that one can get all the basic amplifier functions , i.e., VCVS, VCCS,CCCS,CCVS from this single module.

0.5 micron CMOS process.

+ and – 3V power supplies (Maximum)

sample calculations regarding design and verify with simulation results (HSPICE, level=3)

Minimum gain should be 100 units (for VCCS the unit could be milli mho or micro mho)

a data sheet summarizing important parameters of the amplifier module. Some of these will be

   * Total DC power consumption
   * Total transistor area used
   * Number of external voltage/current sources needed
   * Interconnection hints for obtaining a specific amplifier function (i.e., VCVS)
   * Gain at low frequency and band-width (-3dB) (show test set-up)
   * Input and output resistances (show the test set-up)
   * Overall output-input delay (1pf load) (show test set-up)
   * Overall settling time (1 pf load) (show test set-up)
   * Slew rate (open circuit, 1 pf load) (show test set-up)
   * Input common mode range (voltage or current) for linear operation (show test set-up)

schematics of all the sub-systems employed.
