Abstract
Analog-valued floating-gate transistors are used as trimmable circuit components for modifying and/or controlling the gain, phase, offset, frequency response, current consumption, and/or transfer function of signal pathways in parallel and/or serial processing circuits in radio frequency, analog, or mixed-signal integrated circuits.
Claims2
An amplifier circuit, comprising:
- a signal input node;
- a signal output node;
- and
- a transistor having a source, a drains and a floating gate, the source of the amplifier transistor configured for electrical coupling to said signal output node, and the floating gate of the amplifier transistor configured for electrical coupling to said input node, said amplifier transistor including a readout transistor and a tunneling junction which are configured to remove charge from and/or add charge to the floating gate to thereby enable bidirectional shifting of a readout threshold voltage of the amplifier transistor.
