A MOSFET version of Figure 3 is shown in Figure 4, where MOSFETs M 3 and M 4 operate in ohmic mode to play the same role as emitter resistors R E in Figure 3, and MOSFETs M 1 and M 2 operate in active mode in the same roles as mirror transistors Q 1 and Q 2 in Figure 3. An explanation follows of how the circuit in Figure 3 works.
The use of a cascode (sometimes verbified to cascoding) is a common technique for improving analog circuit performance, applicable to both vacuum tubes and transistors.The name "cascode" was coined in an article written by Frederick Vinton Hunt and Roger Wayne Hickman in 1939, in a discussion on the application of voltage stabilizers.

Fig. 1: Wilson current mirror Fig. 2: Wilson current source. There are three principal metrics of how well a current mirror will perform as part of a larger circuit. The first measure is the static error, i.e., the difference between the input and output currents expressed as a fraction of the input current.
In 1992, version 2.6 changed the definition of layers, but designs created under older versions (up to 2.05) could be converted into the new format using the provided UPDATE26.EXE utility. EAGLE 3.0 was changed to be a 32-bit extended DOS application in 1994. Support for OS/2 Presentation Manager was added with version 3.5 in April 1996. This ...
The sales per average square foot was $85, down from $86 Y/Y. Total auto parts sales reached $4.2 billion, up from $4.12 billion Y/Y. The domestic commercial sales for the quarter reached $1.13 ...
To design the mirror, the output current must be related to the two resistor values R 1 and R 2. A basic observation is that the output transistor is in active mode only so long as its collector-base voltage is non-zero. Thus, the simplest bias condition for design of the mirror sets the applied voltage V A to equal the base voltage V B.
Ben Affleck and Jennifer Garner are continuing to spend time together this holiday season.. The former couple — who share kids Violet, 19, Seraphina, 15, and Samuel, 12 — were spotted out for ...
ABAQUS version 1 was created for a specific client -- Westinghouse Hanford Company which used the software to analyze nuclear fuel rod assemblies. ABAQUS version 3 was released in June 1979. [ 13 ] In the early days, ABAQUS was designed primarily for the nonlinear static and dynamic analysis of structures, and nonlinear steady and transient ...
