摘要

讨论了在100MHz信号带宽下提供±0.25%精度的乘法器设计技术。虽然电路在电流模式下工作，但虚拟地输入允许在低电压下工作。激光切边用于消除vbee不匹配引起的非线性。

A wideband two-quadrant analog multiplier

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.
