JFET Common Source DC Amplifier Temperature Compensation



My app uses a JFET..

What are some ways to temperature compensate a common source JFET DC
amplifier.

'DC' amplifier.

Details:
1) The signal does contain a stable bias voltage.
2) Temp range: 20C to 50C
3) Vout thermal error of +/-10mVdc.
4) BW: DC to 2Mhz

I'm guessing compensation by:
1) PTC or NTC resistor
2) Use another JFET and feed in anti drift.
3) Find a special jfet (IC??) << not an op amp!

Possible ??
