    摘要: In an integrated circuit, a clock monitor circuit detects when an analog clock signal output by an on-chip crystal oscillator has stabilized. The clock monitor circuit uses an envelope follower circuit to monitor the envelope of the analog clock signal and compare the amplitude of the envelope with a predetermined amplitude value. When the predetermined value is reached and the envelope has remained steady for a predetermined time, an oscillator okay signal is generated. If an oscillator okay signal is not detected within another predetermined time, then an oscillator failure signal may be generated.

    摘要: A standard cell layout for a multiple input logic gate includes first through fourth parallel gate electrodes disposed over first and second active regions. The first and second gate electrodes are disposed on a first side of a first axis at first and second distances, respectively, from the first axis, and the third and fourth gate electrodes are disposed on a second side of the first axis at third and fourth distances, respectively, from the first axis. The first distance is greater than the second distance and the fourth distance is greater than the third distance. The third and fourth gate electrodes form a mirror image of the first and second gate electrodes about the first axis.

    摘要: A Read Only Memory (ROM) device includes a ROM array, a row address decoder, a column address decoder, a column multiplexer, and a control circuit. Data is stored in bit cells in the ROM array. The control circuit generates control signals for reading the ROM. The row address decoder selects a word line. The column address decoder enables a bit line. The data is sensed from a bit cell corresponding to the selected word line and the enabled bit line by a corresponding sense amplifier and delivered on a data output pin of the ROM. The control signals for enabling the bit line and the sense amplifier operate at a higher voltage than supply voltage of the ROM. This reduces the ROM read time.
