Amplifier common-mode feedback systems for use with switched-capacitor structures |
摘要 |
Improved differential amplifiers are provided for use with switched-capacitor structures. Amplifier embodiments include a differential pair of high-transconductance transistors for generation of differential currents and routing of common-mode feedback signals along an independent path so that sufficient headroom is provided for other high-transconductance transistors that generate common-mode currents. The differential and common-mode currents preferably generate differential and common-mode output signals in finite output impedances of active loads.
