Abstract: A pipelined analog-to-digital converter includes a first stage circuit and a second stage circuit. The first stage circuit performs an analog-to-digital conversion on an analog input voltage to generate a first output signal including M higher bits among (M+N) bits of a digital output code corresponding to the analog input voltage, and generates a residue voltage corresponding to N lower bits among the (M+N) bits of the digital output code wherein M and N are natural numbers. The second stage circuit includes a residue amplifier configured to sequentially amplifying the residue voltage and a comparison voltage to generate an amplified residue voltage and an amplified comparison voltage.

Abstract: A data transmitting and receiving apparatus includes a coil configured to transmit and receive data through inductive coupling, where a voltage drop across the coil constitutes a sensing signal. The apparatus further includes an input unit configured to generate transmission data and a replica signal in accordance with an input data signal, the transmission data being supplied to the coil. The apparatus still further includes a replica unit configured to generate a compensation signal in accordance with the replica signal, and an output unit configured to extract reception data from the sensing signal using the compensation signal.
