Circuits for the control of output current in an electronic device for performing active biological operations
View Patent ↗A circuit for control of an output current in a multiple unit cell array includes an array of unit cells arranged in rows and columns. Each unit cell includes a column select transistor being adapted for control by a column selector and a row select transistor being adapted for control by a row selector. The column select transistor and the row select transistor are connected together in series to each other and between an output node and a first supply. A return electrode is provided to complete the circuit.
1. A circuit for control of an output current in a multiple unit cell array, comprising:
an array of unit cells arranged in rows and columns, wherein each unit cell comprises:
a column select transistor adapted for control by a column selector;
a row select transistor adapted for control by a row selector, the column select transistor and the row select transistor being connected in series to each other and between an output node and a first supply;
a second column select transistor adapted for control by a column selector;
a second row select transistor adapted for control by a row selector, the second column select transistor and the second row select transistor being connected in series to each other and between the output node and a second supply; and
a return electrode.
2. The circuit of claim 1 wherein the first supply is Vcc.
3. The circuit of claim 1 wherein the second supply is ground.
4. The circuit of claim 1 wherein the row select transistors and the column select transistors are field effect transistors.
