In order to achieve high volume and low unit cost, most integrated circuits are designed to satisfy the needs of as many different user applications as possible. For example, one user of an IF chip might require an on-chip second mixer but no squelch or second local oscillator whereas another user might require all three. For maximum flexibility, the IC designers would include all of these circuits on-chip with some provision for the ability to disable or turn off sections of unused circuitry. Similarly, for digital designs there may be many unneeded circuit functions with unused circuit-enable and logic inputs.
