A technique is provided for making a semiconductor device having a first circuit block. This technique comprises analysing the first circuit block to determine its transfer function. The transfer function is then rearranged to resemble a known type of transfer function of a simpler circuit block whose performance is a known function of one of more parameters of the second transfer function. The value of the or each parameter which achieves a desired performance is derived from the known function and is used to calculate component values of the circuit block to be made so as to form a design. The design is then acted on so as to manufacture the device.
