Abstract
A programmable and non-volatile analog signal storage structure and method are disclosed that employ two non-volatile cells which are arranged as a differential transistor pair. The non-volatile transistor at the positive (or non-inverting) terminal of the amplifier is referred to as the reference cell, while the non-volatile transistor on the negative (or inverting) input of the amplifier is referred to as the storage cell. The structure comprises a storage cell and a reference cell that produces a voltage which is independent of temperature and supply voltage variation. Additionally, the circuit structure is capable of operating at low supply voltage levels (<1.5V).
