    摘要： The present invention relates to a tuning circuit, more specifically to a tuning circuit for continuous-time filter capable of making exact the Gm value to minimize the variation of the cutoff frequency due to the variation of process in the Gm-C type of continuous-time filter. According to the invention, a frequency tuning circuit is provided which comprises integrating means for generating a signal discharging from a first reference voltage to a first predetermined value and a signal charging from a second reference voltage to a second predetermined value; offset sampling means for sampling the offset voltages of the Gm cells by receiving a current multiplied by the offset voltages from the Gm cells included in the integrating means and providing a feedback path between the output nodes and the input nodes of the included Gm cells; comparative signal generating means for generating a comparative signal by generating a reference signal by dividing a clock inputted from the external, receiving the signal discharging from the first reference voltage to the first predetermined value and the signal charging from the second reference voltage to the second predetermined value from the integrating means, and comparing the actual intersection and the target intersection of these signals; and control means for generating a control signal to regulate the Gm values of the integrating means and the offset sampling means by receiving the reference signal and the comparative signal from the comparative signal generating means and detecting the phase differences therebetween.

    摘要： A wireless modem is mounted to a terminal for wireless communication, and specifically controls an internal drive clock to reduce power consumption in an active mode. The wireless modem includes: a wireless core module for transmitting and receiving a radio signal; a modulator for converting data to be transmitted into a wireless transmission signal and transmitting the converted signal to the wireless core module; a demodulator for converting the signal received from the wireless core module into reception data; a synchronizer for synchronizing the signal received from the wireless core module; and a clock controller for generating a drive clock of each of the modulator, the demodulator, and the synchronizer. A low power clock controller is divided into six main functional blocks of a synchronizer, an analog controller, a modulator, a channel decoder, a demodulator, and a channel encoder, and has a feature that a clock is input only when a main functional block operates. As a result, it is possible to minimize power consumption caused by clock switching when an Orthogonal Frequency Division Multiplexing Access (OFDMA) mobile station modem operates in an active mode through the clock controller.

    摘要： Apparatus and system for controllably removing liquid from tofu with no or minimal cracking or deforming. An interior box contains tofu. Interior box is insertable and removable from exterior box. Interior box includes drain(s) for liquid removed from tofu, and resilient spacers on bottom to create space between bottoms of interior and exterior boxes for containing drained liquid and for cushioning tofu when pressed. A cover releasably attaches to top of nested boxes. Telescoping extender extends through cover into interior box. Extender is attached at one end to inside cover and attached at other end through a spring-loaded cap to a press plate. Extender has interior tier cylinder nested within exterior tier cylinder. Extender progressively telescopes interior cylinder out of exterior cylinder, and then telescopes exterior tier cylinder to extend press plate further into interior box to press tofu to release liquid. Spring-loaded cap on extender cushions pressure on tofu.
