Abstract
Current mirror amplifiers are disclosed, each having first and second ports that can be interchanged as to which is input port and which is output port in response to an electric control signal. A chopper-stabilized differential amplifier that uses such a switchable current mirror amplifier as a balanced-to-single-ended signal converter for output signals is disclosed, which chopper-stabilized differential amplifier is particularly suited for the integrating amplifier in a delta-sigma analog-to-digital converter.
