Pulse-Width Modulated CMOS Power Amplifiers
... because they allow for a reduction in the symbol rate of the signal. This reduces the bandwidth occupied by the signals by allowing more than 1 bit of information to be transmitted per symbol at the expense of encoding information in the amplitude domain. For PAs, this is troublesome because the amp ...
