AB  - This paper presents a new pseudo-ternary modulation scheme for bridge-tied-load digital class D amplifiers which is more robust versus output stage distortions compared to existing ternary modulations. The effects of finite rise and fall times and their mismatches have been introduced for a classical ternary modulation scheme, where a large degradation of the dynamic range can be observed, and then extended to reported high performance ternary modulators. It is shown that, even if linearization pulses are inserted to cope with the finite rise/fall time problem, these modulators are somehow impacted by the edge mismatches.
