When is a transistor not a.............

[Dr S Grainger]

Dear All,

	Adding my 10p (not on Euros yet !!) to the diode-connected
	transistor debate the essence seems to be feedback.

	With the base-collector connection made there is a pretty
	solid feedback path (the shunt resistor value = 0) This has the
	effect of producing a 'diode' with a wider dynamic range than
	a 2-terminal device. Also to reduce the resultant circuit's dependance
	on the device parameters

	I wonder also if it improves the noise performance ?
