Patent ID: 8760225

Claim:
A gate driver circuit [ 20 ] for driving gates of output transistors [ 26 ] of a switching radio frequency power amplifier [ 12 ], comprising: an input stage [ 30 ] operative for receiving a bitstream digital data signal [ 16 ] comprising a baseband digital data signal [ 13 ] frequency-translated to a desired carrier frequency [ 11 ] and converting the bitstream digital data signal [ 16 ] into a pair of output stage input signals [ 21 ] encoding the digital data signal [ 13 ]; an output stage [ 32 ] operative for receiving the output stage input signals [ 21 ] and generating nominally complementary output pulse signals [ 17 ] at a pair of output gates [ 22 , 24 ] encoding the digital data signal [ 13 ]; and wherein the output stage [ 32 ] comprises a pair of cascoded CMOS gate drivers [ 36 a - b ] connected in a push-pull configuration.
