1. A decoder comprising:
a demultiplexer receiving a to-be-decoded data signal that is in a pulse amplitude modulation (PAM)-2M format, and demultiplexing the to-be decoded data signal into a number (P) of demultiplexed data signals, where M≥2 and P≥2; and
a number (P) of analog to digital converters (ADCs), each of which is connected to said demultiplexer to receive a respective one of the demultiplexed data signals;
wherein one of said ADCs is an (M+1)-bit ADC, and performs analog to digital conversion on the respective one of the demultiplexed data signals to generate a first decoded signal containing a data portion that is M-bits wide and an error portion that is one-bit wide; and
wherein each of the other one(s) of said ADCs is an M-bit ADC, and performs analog to digital conversion on the respective one of the demultiplexed data signals to generate a second decoded signal containing a data portion that is M-bits wide.
