Abstract:
A regulator comprising a linear regulator. The linear regulator may comprise a preamplifier, a first radio frequency (RF) transistor and a second radio frequency (RF) transistor. An output of the preamplifier stage may be provided to a biasing terminal of the first RF transistor and a biasing terminal of the second RF transistor. Also, the first and second RF transistors may be electrically connected in series between a positive supply voltage and a negative supply voltage.
