Smith chart with graphical construction for analysis of a lumped circuit. The analysis starts with a Z Smith chart looking into R 1 only with no other components present. As R 1 = 50 Ω {\displaystyle R_{1}=50\ \Omega \,} is the same as the system impedance, this is represented by a point at the centre of the Smith chart.
Capacitive coupling from high-voltage power lines can light a lamp continuously at low intensity. In its simplest implementation, capacitive coupling is achieved by placing a capacitor between two nodes. [1] Where analysis of many points in a circuit is carried out, the capacitance at each point and between points can be described in a matrix form.
Mutual capacitance allows multi-touch operation where multiple fingers, palms or styli can be accurately tracked at the same time. [10] Self-capacitance sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently. With self-capacitance, current senses the capacitive load of a finger on each ...
Most analysis methods calculate the voltage and current values for static networks, which are circuits consisting of memoryless components only but have difficulties with complex dynamic networks. In general, the equations that describe the behaviour of a dynamic circuit are in the form of a differential-algebraic system of equations (DAEs).
Capacitive displacement sensors share many similarities to eddy current (or inductive) displacement sensors; however capacitive sensors use an electric field as opposed to the magnetic field used by eddy current sensors [10] [11] This leads to a variety of differences between the two sensing technologies, with the most notable differences being ...

A simple switched-capacitor parasitic-sensitive integrator. Switched-capacitor simulated resistors can replace the input resistor in an op amp integrator to provide accurate voltage gain and integration. One of the earliest of these circuits is the parasitic-sensitive integrator developed by the Czech engineer Bedrich Hosticka. [3]
From January 2008 to December 2012, if you bought shares in companies when Ari Bousbib joined the board, and sold them when he left, you would have a 128.0 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
