Transient Analysis - One of the most complex and intriguing capabilities of the SPICE algorithm is the Transient Analysis. How do we take a collection of resistive and energy-storage components, then find its time response to an arbitrary input waveform? Yes, you could formulate and solve the differential equations to get the response versus time, but SPICE is not a differential equation solver...(spice design added 02/09)
Transimpedance Amplifier - You may have noticed that most circuits work on a convenient principle: Voltage In, Voltage Out. But, what about the large class of sensors, such as a photodiode, that produce a current? Photodiodes may be called into action for applications such as precision light meters or high-speed fiber-optic receivers. If you need to amplify the signal from this type of sensor, you must first convert this current to a useful voltage...(spice design added 02/09)
Transistor Differential Amplifier - Look under the hood of most op amps, comparators or audio amplifiers, and you'll discover this powerful front-end circuit - the differential amplifier. A simple circuit able to amplify small signals applied between its two inputs, yet reject noise signals common to both inputs. This circuit has a unique topology: two inputs and two outputs. Although you can tap the signal from one output only, taking the difference between ...(spice design added 02/09)
