Abstract :
A multiplier design technique affording ± 0.25% accuracy with 100MHz signal bandwidth will be discussed. Although the circuit operates in current mode, the virtual-ground inputs permit operation from low-level voltages. Laser trimming is used to eliminate nonlinearities due to VBEmismatch.
