PROBLEM TO BE SOLVED: To provide self-correcting amplifier output common mode to p-type to n-type transistor strength differences.SOLUTION: According to one embodiment, an improved voltage headroom self-biased receiver is provided. According to one embodiment, tail current sources are biased so as to be cross-coupled with respect to each other. According to one embodiment, startup control is provided to counter defect-induced current and to ensure that the circuit can function properly even with large amounts of defect current. According to one embodiment, a p-channel metal oxide semiconductor (PMOS) tail current transistor is modulated by an n-channel metal oxide semiconductor (NMOS) differential pair virtual negative voltage, and an NMOS tail current transistor is modulated by a PMOS differential pair virtual positive voltage. |
