Clamp and Programmable Load circuit

Default is Clamp setup. 

Clamp protection is limited to current source capability (here 25mA). Above this value, the voltage will start rising again following Vin.
To resume, here voltage will stay between -1V and 5V as long as input current is lower than 25mA.

To use as programable load, swap -1V and 5V sources. 
Both sources can be merged to get only one bias voltage.
In this mode, circuit will source current if Vbias>Vin, and sink current if Vbias<Vin. Source/Sink current depend on curent source value.
