Abstract: A circuit including a first element sampling noise from and discharging noise to a signal line in response to an input signal transitioning on selected edges of a clock signal. A second element samples noise from and discharges noise to the signal line in response to another input signal transitioning on other edges of the clock signal differing from the selected edges of the clock signal such that noise coupled into substrate and supply are independent of the input signal.

Abstract: A driver circuit includes an operational amplifier having an input and an output coupled by a feedback element. A voltage level shifter generates a voltage drop from the operational amplifier output to the operational amplifier input with a current source transistor setting a current controlling the voltage drop across the feedback element. A chopper circuit shifts flicker noise generated by the current source transistor to a higher frequency spectrum.

Abstract: An electrical connector assembly (1) includes a first connector (10) and a second connector (20) mated with the first connector. The first connector includes a first housing (100), and a plurality of first terminals (104) received in the first housing. The first housing includes a protruding portion (102) defining two recesses (1023). Each recess has two first interference blocks (1025). The second connector includes a second housing (200), and a plurality of second terminals (204) received in the second housing. The second housing includes a receiving space (202), for receiving the protruding portion of the first connector. The receiving space includes two projections (2023) corresponding to the recesses of the first connector. Each projection has two first interference blocks (2025) interferentially engaging with the corresponding first interference blocks of the protruding portion. As a result, retention force between the first connector and the second connector is reinforced.
