摘要： A voltage regulator has an input node and an output node, a supply voltage rail, and an output transistor (Mn1) with its drain connected directly to the supply voltage (Vdd) rail and its source connected to the output node (14). A first differential voltage amplifier (A1) with its output (11) is coupled to the gate of the output transistor (Mn1). A control loop and a sense transistor (Mn2) are connected to the output transistor and to behave as a scaled copy of the output transistor in which the output transistor acts as a voltage follower, and in which the drain of the sense transistor is connected to the control loop.

摘要： A voltage comparator (1) has a high switching speed and simplicity of design. It minimizes pulse-width distortion of input digital signals when functioning as a digital input buffer in high speed communications applications. In addition it provides a simple hysteresis circuit (31) that is easily tuneable with a reference current. The hysteresis circuit (31) is dependent on a reference current. This current may be chosen to have a proportionality to temperature, supply, or another selectable parameter, and may be programmable, in order to create the desired hysteresis performance.

摘要： An optical receiver (1) comprises a differential TIA (4) linked with a photodiode (2, 3) providing a current sense signal (I sig_tia ). The receiver is configured to provide to the TIA a sense signal as a sense TIA input (I sig_tia ) and a second input (I dark_tia ) which is a proportion of the maximum sense signal. The proportion input is half of said maximum sense signal. The inputs to the TIA are via cascode circuits (5, 6), thereby providing the advantages of a low input impedance for large area photodiodes at the TIA input, while creating a fully differential signal at the output, and the reduction of TIA bandwidth in burst mode applications, which filters out high frequency noise.

摘要： A receiver has a differential transimpedance amplifier (4) with two inputs and two outputs. The differential transimpedance amplifier (4) provides a differential output and this is peak-detected (15, 16) to provide amplitude reference signals. The differential transimpedance amplifier output and the amplitude reference signals are fed to a differential summing amplifier (10), which provides a fully differential signal to a comparator, or to an automatic gain control circuit (5) to regulate the differential transimpedance amplifier gain. The differential summing amplifier (10) output is a fully differential signal, thereby having lower distortion for DC and burst mode receiver applications.

摘要： A connector includes a main body, and a pair of sockets. Each socket includes a pair of opposed resilient walls in the overall configuration of a split tube. The connector also includes a transversely sliding clamp with two tapered slots, located so that one of the sockets passes through each slot. After fiber terminations are pushed into the sockets through the clamp slots, the clamp is slid in a plane across the socket axes so that the narrower ends of the slots engage the opposed split tube resilient walls of each socket. This squeezes each socket so that the opposed split tube resilient walls press against the associated fiber termination and retains it in place. The sockets may have guide slots for guiding clamp movement. The clamp moves in a translational movement, but in another example the clamp rotates in the lateral plane to squeeze the sockets.

摘要： An optical connector includes four main components, namely a clamp; a housing into which the clamp slides; two optical elements, a transmitter and a receiver; and an EMI metal shield surrounding the elements. The clamp has two parallel through holes for receiving fiber terminations, each through-hole having a generally conical mouth for convenient guidance of a fiber termination. Inside of the through-holes there are side resilient clamp members, and there is a single central clamp member. The clamp is of moulded plastics construction, and the clamp members are resilient in the lateral plane. The central clamp member on the other hand has little flexibility and remains essentially static throughout the clamping operation. Each resilient clamping member has a tooth at its end for snap-fitting engagement with the housing at open and closed positions. Fiber terminations are inserted through the clamp mouths and the through-holes and into the sockets of the housing. The clamp is then simply pushed inwardly so that teeth in the socket walls bite into the fiber claddings.

摘要： A beam expander (100) of the invention is a single moulded transparent plastics body having a planar light input surface (101), circular in end view, upon which input light is incident, and a tapered outer reflection surface (102) forming a frusto-conical shape. A planar light output surface (103) faces in the longitudinal or axial direction and a tapered reflection inner surface (104), in a frusto-conical shape, is formed by an on-axis recess in the moulded body. All of the surfaces have an axis on a longitudinal axis of the device, namely the optical axis. Light is directed by the inner reflection surface radially towards the outer reflection surface, where it is again reflected back to axial, but with a much longer beam diameter. The overall length (t) of the beam expander is very short.

摘要： An optoelectronic device (30) has a lead frame (31) and a circuit board (34) on the lead frame. A moulded body (32) forms a lens (33) over an optoelectronic component (39). The component is placed on the lead frame (31) within an aperture (37) of the circuit board. The aperture may include a conductor on the inward-facing surface to contribute to screening of the optoelectronic component, and there may additionally be wires (51) over the aperture to contribute to screening. By virtue of being within an aperture the optoelectronic component may be physically further from the lens (33) surface, there is additional space for conductors, and there may be additional electromagnetic interference screening.
