Provided is a complementary metal oxide semiconductor (CMOS) inverter layout for increasing an effective channel length. The CMOS inverter layout may include first and second conductive MOS transistors respectively formed in first and second active regions, metal lines electrically connecting the first and second conductive MOS transistors, and one or more gate electrodes electrically connecting the gates of the first and second conductive MOS transistors. The widths of one or more gate electrodes may be set to a reduced and/or minimum feature size to reduce and/or minimize a process variation and a layout area of the CMOS inverter. Also, the first and second conductive MOS transistors may be connected in series via the metal lines to increase an effective channel length, thereby realizing a layout of the CMOS inverter having a longer delay than a conventional CMOS inverter.

A high-speed gated flip-flop includes a latch configured to generate a data output signal (Q) in response to a data input signal (D) and a pair of true and complementary clock pulses (GCP,GCPB). These clock pulses are provided by a clock generator responsive to a periodic clock signal (CK). A control circuit is also provided. The control circuit is coupled to a feedback node (ND2) in the pulse generator. The control circuit configured to selectively enable the pulse generator in response to an enable signal (/EN). The pulse generator is configured so that an active transition of the true clock pulse (GCP) is fed back to the feedback node (ND2) in a manner that resets the pulse generator and terminates the true and complementary clock pulses in-sync with the active (e.g., low-to-high) transition of the true clock pulse (GCP).

Disclosed herein is a similar speaker recognition method and system using nonlinear analysis. The recognition method extracts a nonlinear feature of a sound signal through nonlinear analysis of the sound signal and combines the nonlinear feature with a linear feature such as spectrum. The method transforms sound data in a time domain into status vectors in a phase domain and uses a nonlinear time series analysis method capable of representing nonlinear features of the status vectors to extract nonlinear information of a sound. The method can overcome technical limitations of conventional linear algorithms. The recognition method can be applied to sound-related application systems other than speaker recognition systems.
