Systems and methods for implementing pseudo-resistors with programmable resistance and controlled leakage

An apparatus comprising:

• a first resistor unit comprising a first terminal and a second terminal, the first resistor unit being configured to provide a first resistance between the first terminal and the second terminal, the first resistor unit further comprising a first transistor coupled to the first terminal and a second transistor coupled to the second terminal;
• a first reset unit coupled in series with the first resistor unit, the first reset unit being configured to provide a second resistance between the first terminal and the second terminal in response to a first control signal, the second resistance being lower than the first resistance;
• a first circuit coupled to the first resistor unit, the first circuit being configured to adjust the first resistance by providing a first bias voltage to the first resistor unit;
• and
• a second circuit coupled to the first circuit, the second circuit being configured to adjust the first bias voltage by providing a first bias current to the first circuit.
