A circuit for charge-balanced current-controlled stimulation. The circuit includes a transistor differential pair, a first current mirror, a second current mirror, and a third current mirror. The transistor differential pair includes a first differential input node, a second differential input node, a first differential output node, a second differential output node, and a common node. The transistor differential pair is configured to generate a first differential current that passes through the first differential output node and a second differential current that passes through the second differential output node. The first current mirror is configured to generate a first mirrored current based on the first differential current. The second current mirror is configured to generate a second mirrored current based on the second differential current. The third current mirror is configured to generate a third mirrored current based on the first mirrored current.
