摘要

通过对放大器输入级采用共模线性化技术，优化了宽带大信号失真。采用6 GHz f/sub / T/介电隔离互补双极工艺制作了一种运算放大器，在2 V/sub / pp/ 10 MHz输入信号、2 GHz GBW和500 /spl mu/V V/sub / os/下，实现了1 nv//spl径向/Hz电压噪声，优于90 dBc失真。

An opamp with common-mode linearized input stage

Wideband large-signal distortion has been optimized by applying a common-mode linearization technique to the amplifier input stage. An operational amplifier has been fabricated in a 6 GHz f/sub T/ dielectrically-isolated complementary bipolar process that achieves 1 nv//spl radic/Hz voltage noise, better than 90 dBc distortion for a 2 V/sub pp/ 10 MHz input signal, a 2 GHz GBW, and 500 /spl mu/V V/sub os/.
