Abstract: An integrated circuit chip is provided. The integrated circuit chip includes a pad, a first resistor, a second resistor, a first switch, a second switch and a controller. The first resistor and the first switch are serially connected between the pad and a first reference voltage terminal. The second resistor and the second switch are serially connected between the pad and a second reference voltage terminal. The controller selectively turns on and off the first and second switches according to an error determining mechanism. The error determining mechanism determines whether an error condition associated with the pad is present.

Abstract: A portable electronic device having automatic power supply mode switching is provided. The portable electronic device includes a micro-sensor and a control circuit. The control circuit controls operations of the electronic device, the micro-sensor senses whether the electronic device is carried or worn by a user. When the electronic device operates in a normal mode, and if the electronic device is not carried or worn for a time longer than a buffer period of a predetermined interval, the control circuit switches to a sleep mode, which results in lower power consumption.

Abstract: An apparatus for demodulating a digital video signal applied to a receiving end of an Orthogonal Frequency-Division Multiplexing (OFDM) communication system is provided. The apparatus receives a plurality of OFDM symbols, and stores a plurality of data sequences in an external memory. The apparatus includes a de-interleaver, that de-interleaves the data sequences to generate a plurality of de-interleaved data sequences; a decoder, coupled to the de-interleaver, that generates a plurality of data streams according to the de-interleaved data sequences; a reconstruction apparatus, coupled to the decoder, that reconstructs the data streams into a transport stream; and a memory interface unit, coupled to the external memory, that accesses the data sequences and the data streams from the external memory. The external memory includes a de-interleaving buffer that stores the data sequence, and a data reconstructing buffer that stores the data streams.
