摘要

本文介绍了一种可编程增益放大器(PGA)电路，其动态增益范围为98 db，增益步长为2 db，在3v电源下由6位增益控制位控制。它是在0.5-/spl mu/m 15 ghz f/sub T/ Si BiCMOS工艺中制造的，与增益设置无关，可产生13 ma的恒定电流。电路占用的有源芯片面积为400-/spl mu/m /spl倍/1170-/spl mu/m。在最大增益设置下测量噪声系数(NF)为5db。

A 50-MHz 98-dB dynamic-range dB-linear programmable-gain amplifier with 2-dB gain steps for 3-V power supply

A programmable-gain amplifier (PGA) circuit introduced in this paper has a dynamic gain range of 98-dB with 2-dB gain steps and is controlled by 6-bit gain control bits for a 3-V power supply. It has been fabricated in a 0.5-/spl mu/m 15-GHz f/sub T/ Si BiCMOS process and draws a constant current of 13-mA, independent of the gain settings. The active die area taken up by the circuit is 400-/spl mu/m /spl times/1170-/spl mu/m. A noise figure (NF) of 5-dB was measured at the maximum gain setting.
