Abstract
A low-noise output stage for an electronic circuit integrated on a semiconductor substrate is disclosed. The low-noise output stage comprises a complementary CMOS transistor pair including a P-channel pull-up transistor and an N-channel pull-down transistor, connected across a first terminal of the electronic circuit to receive a supply voltage, and a second terminal of the electronic circuit to receive a second reference potential. The transistors are connected together to form an output terminal of the electronic circuit for connection to an external load. The pull-down transistor is formed in a three-well structure to prevent propagation of a discharge current from the external load through the semiconductor substrate.
