I hope this theory 'll help to get clear from Voltage and current sources
Most sources of electrical energy (the mains, a battery, ...) are best modeled as voltage sources. Such sources provide constant voltage, which means that as long as the amount of current drawn from the source is within...
Operation Voltage(VDD) :( take pulse wise linear source and dimension it, so that after some time(100us) it goes to from 0 to 5 Volts)...
Then its starts oscillating
Make the diode in to two series connecte diode, Its better for macthing (in layout)
Length of diode connected to GND/VDD must be the same as current source
Ciao.
Added after 22 seconds:

Hallo Hallo
Bipolar is Ok , but how to get rid of base current? Anyways it depends , if u have bicmos technology.
Generally Take mos as Diff pair and try to dimmension it , so that it has enough gm/B.W/ 1%matching error. Don't forget to concentrate on ur current load(u have to...
