We describe a modified lateral approach to the hip which exploits the function continuity of gluteus medius and vastus lateralis and their dense crescentic attachment to the greater trochanter. The gluteus medius is not incised or split, but is detached and mobilised with gluteus minimus as one unit. This facilitates reattachment of the glutei and helps to(More)

Prerequisites: ECE-711 and ECE-403 or equivalents. It is assumed that the students are familiar with the following topics: 1. Solid-state device operation and circuits: P-type and N-type semiconductors, diodes, bipolar junction transistors, and MOS field-effect transistors. Small signal models and their associated parameters as well as their primary(More)
–A current amplifier is used to realize a voltage amplifier having an improved high frequency response and slew rate capability. It is shown that the closed loop bandwidth is independent of the closed loop voltage gain. The design and application of a unity gain and a high gain current amplifier to voltage signal processing circuits are given. The results(More)
An approach to integrated mixed-mode simulation is described in which the popular SPICE circuit simulator is extended to analyze digital circuits at the gate, functional or behavioral levels. The analogue-to-digital conversion is provided by (multilevel) parameterized " thresholders " which assign digital signals to subranges of voltages determined by a set(More)

was not programmed, but they were erased using ultraviolet light while connecting all circuit terminals to ground. A scheme for rail-to-rail continuous-time input signal swing using MIFGTs has been proposed. This scheme provides constant g m. Single-ended and fully differential op-amp architectures based on this scheme and with a novel class-AB output stage(More)
Twenty-three preserved cadaver upper limbs were dissected to show the level of the nerve supply to flexor carpi radialis and the extent of exposure of a new approach to the flexor surface of the distal radius. We describe a new approach to the flexor surface of the distal radius in which both the radial artery and the median nerve are protected by muscles(More)
