Abstract
A transimpedance amplifier (TIA) device design is disclosed. Symmetric components include first and second resistors R, R, R, R, R, R, and R, and transistors Q-Q. An optional mixer or cascode adds transistors Q-Q. Values for resistor components Rprovide extended feedback gain tuning in a TIA-based current amplifier or mixer implementations without greatly affecting the input impedance or requiring more attenuators. Example values for resistor components Rrange from about 50 to about 350 ohms.
