  • Patent number: 9438179
    Abstract: An amplifier apparatus includes a differential input pair, a current source, and a load. The differential input pair includes first and second transistors, and an auxiliary transistor. A control terminal of the first transistor receives a reference voltage. A first terminal of the second transistor is coupled to the first terminal of the first transistor, and a control terminal of the second transistor receives an input voltage. A first terminal of the auxiliary transistor is coupled to a first terminal of the first transistor, a second terminal of the auxiliary transistor is coupled to a second terminal of the first transistor, a control terminal of the auxiliary transistor receives a control voltage, and a base terminal thereof receives a power supply voltage. The current source and load are respectively coupled to the first terminals and second terminals of the first and second transistors.

  • Patent number: 9361258
    Abstract: A common interface (CI)/conditional access (CA) module is used to transmit a conditional access data/command and a transport stream in an interleaving manner between a common interface card and an integrated circuit module having a conditional access module. With the aid of the CI/CA module, a same port can be shared for transmitting the conditional access data/command and the transport stream, instead of using two different and separated ports.

  • Patent number: 9331674
    Abstract: A multi-phase signal generator and a multi-phase signal generating method thereof. The multi-phase signal generator includes a signal generator, a first comparator, a second comparator and a logic operation circuit. The signal generator generates a periodic signal. The first comparator receives the periodic signal and respectively compares the periodic signal with a first reference voltage and a second reference voltage to generate a first output signal. The second comparator receives the periodic signal and compares the periodic signal with a first threshold voltage to generate a second output signal. The logic operation circuit performs logic operations on the first output signal and the second output signal so as to generate a plurality of first phase output signals.

  • Publication number: 20020073129
    Abstract: An integrated multi-component scheduling process is invented that may emulate various scheduling methods. For general purpose operating systems, the integrated scheduling method can be used to provide more powerful capabilities as many commonly used scheduling methods, including priority-driven, time-driven, and share-driven methods. With a multi-component structure, scheduling policy components can be separated from scheduling mechanism components in an operating system scheduler. The integrated scheduling method can also be used to combine several scheduling policies into one method.
