Abstract:
A current-saving CMOS signal input buffer is provided, having at least two CMOS output transistors (each having an input) connected in complementary fashion with a common output taken therebetween, complementary current mirrors coupled to the output transistor inputs, an input signal capacitively coupled to at least one of the output transistor inputs, a reference impedance coupled between the complementary current mirrors, and isolation impedances coupled between the complementary current mirrors and the output transistor inputs.
