				Amplifiers perform precision divide by 2 circuit: 03/06/03  
				EDN-Design Ideas / The classic implementation of a 
				voltage-halving circuit uses two equal-value resistors. Using 1% 
				resistors provides a divider output with 2% accuracy. For most 
				applications, this performance is cost-effective and more than 
				adequate. However, when you need extreme precision, this 
				approach requires correspondingly accurate resistors and can 
				become expensive... |
