    摘要: A Low-Voltage Differential Signaling (differential signaling) driver circuit (10) comprising enable circuitry for enabling and disabling the differential signaling driver circuit (10) in accordance with an control signal is described. The differential signaling driver circuit (10) comprises: a differential output (12, 13) connected or connectable to a differential signaling receiver circuit via a differential transmission line; current control circuitry (14) for driving a signal current through the differential output (12, 13) in accordance with a driver signal; feedback circuitry (16) for driving the current control circuitry (14) to counteract a difference between a common mode voltage of the differential output (12, 13) and a reference voltage from a reference voltage provider; and the enable circuitry (18). The feedback circuitry (16) comprises a common mode node (20) for providing the common mode voltage (Vcm), a reference input (22) connected or connectable to the reference voltage provider, and a feedback input (24). The enable circuitry (18) is arranged to connect the feedback input (24) to the common mode node (20) when the differential signaling driver circuit (10) is in an enabled state and to the reference voltage provider when the differential signaling driver circuit (10) is in a disabled state. A method of enabling (5.1) and disabling (5.2) a Low-Voltage Differential Signaling (differential signaling) driver circuit (10) is also proposed.

    摘要: Embodiments generally relate to a conversion arrangement, a driver arrangement, and a method of producing a complementary complementary metal-oxide-semiconductor (CMOS) output signal for driving a modulator device. The conversion arrangement includes a differential amplifier configured to produce a first amplified signal based on the differential input signal, and at least two transimpedance amplifiers (TIAs) coupled with respective outputs of the differential amplifier and configured to produce a second amplified signal based on the first amplified signal. Respective bias voltages for the TIAs are based on the first amplified signal. The conversion arrangement further includes a common-mode feedback arrangement coupled with outputs of the TIAs and configured to control the first amplified signal based on the second amplified signal, thereby controlling the bias voltages, wherein the complementary CMOS output signal is based on the second amplified signal.
