Presents 1,000 meg of output impedance while supplying up to 200 no of temperature-compensated current. Germanium diodes serve as compensating network drawing 1.3 ma. Based on fact that matched transistor pairs have base-current temperature coefficients that are predictable as function of operating current-C. C. Hanson, Low. Drift Current Generator Compensates for Temperature, Electronics, 39:12, p 108-109.
