Latest Patents

One of Boles' latest patents is a low-noise current source. This invention provides a current source designed to limit noise and offset. In one embodiment, a source transistor is utilized, with current sourced at the drain. A feedback network runs from the source node to the gate, producing voltage gain through a transconductance, such as a transistor. The design also incorporates appropriate capacitors and two pairs of switches to facilitate offset cancellation by toggling between gain and clamp modes in a switched capacitor architecture.

Another significant patent is a system and method for improving speed and power in a switched-capacitor amplifier. This invention features a multiplying analog-to-digital converter (MDAC) that reduces power consumption by at least 2.3 times through an improved feedback factor. The amplifier employs a feed-forward approach, where the input capacitor, also known as the sampling capacitor, is buffered by a common gate amplifier. This design enhances bandwidth by eliminating input and parasitic capacitance terms from the global feedback loss. Additionally, the amplifier may utilize alternate forms of local compensation, such as cascode compensation, and includes methods to reduce parasitic capacitance with a buffer.
