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. |
