Abstract (en)
[origin: WO2023019015A1] An amplifier (300) includes a first stage (302) and a second stage (304). The first stage (302) includes a first output, and a second output. The second stage (304) includes a first transistor (310), a second transistor (312), and a common-mode circuit (336). The first transistor (310) includes a drain coupled to the first output of the first stage (302). The second transistor (312) includes a drain coupled to the second output of the first stage. The common-mode circuit (336) includes a reversible current mirror circuit coupled to the drain of the first transistor (310) and the drain of the second transistor (312).
