WebWIEN BRIDGE OP-AMP Figure 6.3 Note that this circuit uses positive feedback. For negative feedback (e.g. the op-amp), we have seen that the closed loop gain is ACL = € A 1+Aβ where A is the op-amp open loop gain, and β is the transfer function of the negative feedback network. Frequency stability requires that the condition Aβ = -1 be avoided. http://www.bushorchimp.com/s-op-amp-circuit-design
