    摘要: An electrostatic discharge (ESD) protection circuit includes an MOS transistor acting as a trigger for the circuit. A drain region of the MOS transistor is formed by an N-type heavily doped impurity region which overlaps an N-type well region. Further, a P-type heavily doped impurity region is formed in the N-type well region. The N-type and P-type heavily doped impurity regions are electrically connected to an input/output pad. The ESD protection circuit exhibits a reduced input capacitance at the pad, and a reduced breakdown voltage of the MOS transistor.

    摘要: A delay locked loop (DLL) circuit has a first delay line that delays a received external clock signal for a fine delay time and then outputs a first internal clock signal; a duty cycle correction unit that corrects a duty cycle of the first internal clock signal and then outputs a second clock signal; a second delay line that delays the second clock signal for a coarse delay time and then outputs a second internal clock signal; and a phase detection and control unit that detects the difference between the phases of the external clock signal and the fed back second internal clock signal, and controls the fine delay time and the coarse delay time. The DLL circuit performs coarse locking and fine locking by using different type delay cells, and thus consumes a small amount of power and robustly withstands jitter and variation in PVT variables.

The upper antenna has a coupling groove at one end. The RFID chip contains information of an object which can be communicated with a reader device. One end of the RFID chip is coupled with the projection of the lower antenna and the other end is coupled with the groove of the upper antenna. The spacer is between the antennas to isolate the antennas electrically. The antennas are combined on both sides of the spacer in parallel. The RFID chip is connected with the antennas and fitted on a top side or a bottom side of the spacer so that active signals are transmitted through the antennas to send the information in the RFID chip to the reader device.

    摘要: A delay-locked loop (DLL) circuit includes a standby signal generating circuit, a front stage circuit, and a back stage circuit. The standby signal generating circuit generates a first standby signal and a second standby signal in response to an active signal, a crock enable signal, a first column address strobe (CAS) latency signal, and a second CAS latency signal. The front stage circuit compares the phase of an external clock signal and the phase of a feedback signal and delays the external clock signal based on the phase difference between the external clock signal and the feedback signal to generate a first clock signal. The back stage circuit executes interpolation and duty-cycle correction on the first clock signal.
