Abstract:
An integrated circuit (IC) having a source follower comprising:a first transistor having a drain coupled to a first supply voltage and a gate coupled to a first input; a second transistor having a drain coupled to the first supply voltage and a gate coupled to a second input which is complementary to the first input; a third transistor having a gate coupled to the second input, a source coupled to a second supply voltage which is less than the first supply voltage, and a drain coupled to a source of the first transistor and forming a first output; a fourth transistor having a source coupled to the second supply voltage, a drain coupled to a source of the second transistor and forming a second output which is complementary to the first output; a first pull-up transistor coupled between the first output and the first supply voltage; and a second pull-up transistor coupled between the second output and the first supply voltage.
