Simulate input offset Current for Current mirrors - 06/24/04 EDN Design Ideas /
(added 1/05) Simulating the output-offset current of a current mirror is
straightforward. You simply have to apply an input current, measure the output
current, and calculate the difference. This output-offset current, however, is not
equal to the input-offset current, especially when the circuit is not a 1-to-1
mirror.... |

electronics: if it's portable, it likely to be battery powered, and your circuit must
be designed to perform in a single-supply world. The key to single-supply design is in

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

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

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) |
