Patent abstract
A circuit topology including stacked power amplifiers (e.g., class D PA cells) in a ladder arranged in a house-of-cards topology such that the number of stacked-domains follows a decaying triangular series N, N−1, N−2, . . . , N−i from a fixed ladder to an ith ladder to provide a 1:(i+1) voltage conversion ratio, each stacked domain outputs its power via a flying domain power amplifier cell, and each ladder balances stacked domains of a prior ladder and combines power from all prior ladders.
