Abstract

The invention discloses a digital power amplifier array and a control method thereof, and relates to the technical field of chip design. Comprising a power amplifier unit and a balanced four-in-one power synthesis unit, the power amplifier unit comprises a first MSB power amplifier unit, a second MSB power amplifier unit, a first LSB power amplifier unit and a second LSB power amplifier unit. The first MSB power amplifier unit and the first LSB power amplifier unit form a power amplifier sub-array A, and the second MSB power amplifier unit and the second LSB power amplifier unit form a power amplifier sub-array B. According to the invention, the bit of the output signal can be increased by one bit on the premise that the array scale is the same and the saturation output power is not reduced.
