摘要： A data recovery circuit and a method thereof, which are capable of reducing locking time and jitter, are provided. The data recovery circuit includes a frequency-locked loop, a locking detector, a delay-locked loop, and a data determination circuit. The frequency-locked loop locks the frequency of an internal clock signal fed back thereto in response to an input signal with the frequency of the input signal and generates a frequency locking signal representing that the input signal is frequency-locked with the internal clock signal. The locking detector determines whether the frequency of the internal clock signal is in a predetermined frequency range of the input signal in response to the frequency locking signal and generates a phase control signal. The delay-locked loop is controlled by the phase control signal, locks the phase of the internal clock signal with the phase of the input signal, and generates a recovery locking signal. The data determination circuit receives the recovery locking signal as a clock signal, receives the input signal in response to the clock signal, and outputs the input signal as output data.

摘要： A floating detection circuit detects the floating state of an input node which can receive an externally applied DC input signal, and includes a pulse generator, a counter and a floating state discriminator. The pulse generator is coupled to the input node and supplies a pulse signal to the input node when the input node is in a floating state. The counter receives the pulse signal and counts the number of pulses included in the pulse signal during predetermined intervals. The floating state discriminator compares the number of pulses with a predetermined reference number, so as to produce a floating detection signal, wherein the floating detection signal indicates whether or not the input node is in a floating state. A semiconductor circuit includes this floating detection circuit and a DC level detector. The floating detection circuit included in the semiconductor circuit detects the input node state during a first period and produces the floating detection signal during a second period. The DC level detector is coupled to the input node and measures the level of the DC signal applied to the input node during the second period when the input node is not in a floating state.
