Patent ID: 8487695

Claim:
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.
