    摘要: An output circuit (12) converts a pair of current signals supplied to a pair of common nodes (NCa and NCb) into a pair of voltage signals (VOa and VOb). In each of input buffer circuits (11, 11, ···), a constant current generation section (101) generates, in an output mode, a pair of constant currents in a pair of current paths going from a pair of intermediate nodes (NMa and NMb) to a reference node (VDD1), and stops the generation of the pair of constant currents in a cutoff mode. A voltage-to-current conversion section (102) generates, in the output mode, a pair of input currents corresponding to a pair of input signals (Sa and Sb) in a pair of current paths going from the pair of intermediate nodes (NMa and NMb) to a reference node (GND) to thereby generate a pair of current signals (Ia and Ib) in a pair of current paths going from the pair of intermediate nodes (NMa and NMb) to the pair of common nodes (NCa and NCb), and stops the generation of the pair of input currents in the cutoff mode.

    摘要: A pass-gate (600) has a passageway between an input node (102) and an output node (104). The pass-gate (600) selectively opens or closes the passageway for a signal at the input node under control of a voltage. The pass-gate has a field-effect transistor (106) with a gate electrode (114) and a current channel (110). The current channel (110) is arranged between the input node and the output node. The gate electrode (114) receives the voltage. The pass-gate is configured so as to have the voltage at the control electrode (114) substantially follow the signal at the input node when the passageway is open to the signal.

    摘要: An integrated circuit can be switched between operating modes without the need for a dedicated mode selection pin. A circuit for operation at a specified maximum supply voltage comprises first (DVDD) and second (DVSS) supply- terminals, a first signal input (inputl) for application of a regular input signal, a second signal input (input2), and an output. The circuit further comprises a multiplexer (Mux)with first and second inputs connected to the first and second singnal output. The control circuitry detects a voltage at the first signal input that exceeds the specified maximum supply voltage by a given amount and, in response, applies a drive signal to the input of the gate circuit. With such a circuit design, a relatively high voltage applied to the first signal input will switch the circuit to another operating mode, such as a test mode.

    摘要: Disclosed are a high speed serializing-deserializing system and a method thereof. The high speed serializing-deserializing system includes: a serializing unit including a plurality of serializers, generating a strobe signal, and multiplexing and converting N bits of parallel data into serial data; a transmission link transmitting the converted serial data and the strobe signal from the serializing unit; and a deserializing unit including a plurality of deserializers, and converting the serial data from the transmission link into the N bits of parallel data with the strobe signal from the transmission link. When serializing N bits of externally supplied parallel data with a rate of N:1, the N may be set to one of various integers. Although the N is extend to a large number such as 16, 32, and the like, the performance is not deteriorated and serialization-deserialization is possible. Accordingly, a window time per one data may be decreased to reduce a total delay of a serialization, to increase a bandwidth of a link, and to improve the robustness of the serialization-deserialization.
