Circuit Performs High Speed Voltage to Current, Current to
Current Conversion: 07/25/02 EDN-Design Ideas / The
circuit in Figure1performs active voltage-to-current conversion
or acts as a variable-gain current mirror with high precision
and bandwidth. A typical application is testing high-speed ICs
or other devices that have inputs designed to be driven from
current-steering DACs to enable a modulated voltage source to
control the devices.
Voltage-To-Current Converter Works From A Single-Supply Rail:
02/17/03 Electronic Design - Ideas for Design /
Voltage-to-current converters feeding to grounded loads often
find their way into industrial measurements and control
applications. The conventional textbook circuit needs both
positive and negative-supply rails.
