Differential source follower having 6dB gain with applications to WiGig baseband filters

A differential amplifier comprising:

• a first upper device and a first lower device series coupled between two power supplies;
• a second upper device and a second lower device series coupled between said two power supplies;
• a first DC voltage enables said first upper device and said second upper device;
• a second DC voltage regulates current flow in said first lower device and said second lower device;
• said first upper device and said second lower device coupled to an AC signal component;
• said first lower device and said second upper device coupled to a complement of said AC signal component;
• a first output signal between said first upper device and said first lower device;
• a second output signal between said second upper device and said second lower device;
• all said devices are same channel type;
• a first RC network coupling said AC signal component to said first upper device;
• a second RC network coupling said AC signal component to said second lower device;
• a third RC network coupling said complement of said AC signal component to said first lower device;
• and
• a fourth RC network coupling said complement of said AC signal component to said second upper device, whereby
• said first RC network is equivalent to said fourth RC network and said second RC network is equivalent to said third RC network.
