I was trying to construct a 10x10 cross bar switch using relays -- something like:
Question: is it possible to construct this by using solid state components (power transistors?) -- and if it is how would one go about doing it?
Would appreciate any pointers.
- The target application was to be able to wire together discreet analog components: say OpAms, diodes, transistors
- I was trying to build a hybrid analog-digital computer -- just for fun -- where the digital side would wire together the analog components using a crossbar switch. Using relays becomes very expansive very quickly say if I wanted to have a 100x100 crossbar.
- An attempt at specs: V=36V, Imax = 10mA R ~= 0 (approaching zero -- a few Ohms should be fine) f ~= 0 Hertz [you switch once every few seconds or minutes] -- Note these are what I think would be ideal, a subset or partially covering set should do for now too
- So I the cross-bar or equivalent switching fabric could be an Integrated Circuit
- The Analog components (discreete) that the will connected to the switching fabric will include: Resistors, Capacitors, OpAms, Transistors, Diodes, Differential Amps, Voltage Summers (if I remember from my undergrad?)
- A typical example of circuit that I want to wire together using such a cross bar is below:
