In addition to their actual operation parameter
transconductance, active electronic key components such as
vacuum tubes, field effect transistors, and bipolar transistors
demonstrate diverse negative parameters. In applying the socalled
Diamond structure, the user can obtain an improved
current source with reduced disturbance parameters, as well
as a programmable transconductance independent of temperature.
Standard applications for the Diamond current
source (DCS) can be found in buffers, operational amplifiers
with voltage or current feedback, and transconductance
amplifiers. The DCS simplifies the design of electronic
circuits with bandwidths of up to 400MHz and slew rates of
3000V/ms with a low supply current of several mA.
